I cannot recommend Shift Fast highly enough—everyone was great to work with on my install. Garrett answered every single question I had about adding an AOS and boost controller, ordered parts, and recommended another local shop for a carbon cleaning treatment prior to my install and tune. I chose this shop initially because it is one of the places where Junior Barrios (JR Tuned) tunes vehicles, and I couldn’t be happier with the entire experience. Dave is a good guy and very knowledgable, and I had a great time talking with him about a wide range of subjects. Brandon installed the AOS and EBCS and did a fine job. The tune I received from Junior is awesome—it really woke my ride up and he opened up plenty under the curve for me—no more fine knock learn, and my daily driver is even more fun to drive than it was before. In short, if you have a Subaru, take it to these guys and you’ll be in great hands. I drove over three hours to Shift Fast, and I’ll be happy to make the trip again. Thanks, Dave, Garrett, Brandon, and Junior!

You cant go wrong with this shop. They are honest hard working guys. They have a ton of knowledge and experience. They exceeded my expectations

Ive spent a lot of time and money with this business over time and cannot think of a single negative experience with them. They know their work inside and out and never take shortcuts. Their customer relations are some of the best Ive had and they always take the time to discuss their work with me and always tell it straight. They stand behind their work and look out for their customers. It is the only shop I recommend to anyone who needs work or tuning on any of the platforms they service.

These guys are amazing, they work closely with JNA Performance in SC and both will make sure you are taken care of. I drove 5 hours to see them, totally worth it. They put in the work to make sure your car is running the best it can. Can’t recommended them enough.

A great shop with knowledgeable tuners and mechanics that stand behind their work, which is rare to find. They adjusted their schedule in accordance to mine which is also rare, as well as doing a great job. If you own a Subaru and you want it to get tuned or work done, go here. They also work on other cars as well but I will only speak of what I drive. Thank you guys for the awesome service and work, I will be returning.

Thank you ShiftFast Automotive and Performance!Tuned the RAM 1500.

Needed injectors flow tested. The staff were very professional. Injectors were returned to me faster than expected and explained everything that was the issue. Because of the feedback was able to get my baby back on the road. I will use them again when needed. Thank you for the help Shiftfast!!!!

Answers all questions with extreme professionalism. Cant wait to have my car serviced here.

These guys are great I 100% recommend working with them if you are a Subaru driver. They dropped a RA block in my sti and didn’t waste any time dropping it in once all the parts came in. Very professional, cooperative, they respond within minutes and friendly as well👍 -Matt

Great atmosphere, Great group of guys, and are dedicated to exceed all expectations on any repair or build you have. Go above and beyond to make sure your car leaves damn near perfect with no issues. I brought in my 2006 Evolution 9 MR that a previous shop tried building and completely ruined the car. Stew and the guys turned this thing around and brought back hope and potential for it and has been great ever since I got it back. JR tuned it and made right at 800 horsepower with no issues and drives like stock. I highly recommend these guys over anyone and will continue to have my business for any future repairs or any builds I choose to do. Cant go wrong with shift fast!

I went out of my way to drive 3 hours, one way, just to have these guys take care of my car, no funny business with them, they took care of my Subaru with quick Turn around & all my power needs, don’t go anywhere else, these guys are all business & no play, money well spent! Stop reading & head over there already!!

ALWAYS A PLEASURE TO DO BUSINESS WITH. NEVER BEEN SO HAPPY TO SPEND MY MONEY AT A FACILITYLIKE THIS. BEST TUNING AROUND...

Dave is a great guy and the type of person who you can trust will treat you fairly. Ive not worked with anyone here but they have all been friendly. Dave will be my trusted tuner and my go to guy for the work that I cannot do myself. Thanks shift fast!

These guys are the best in the area, they worked on my 06 WRX and I have nothing but good things to say, such great job that even now after I moved 700 miles away from them I seriouly considered taking my second Subie all the way from NJ so they can do my build.But Stewart recommend I go to Prime Motoring which also one of the shops that JR works with and even thought I can no loger take my car to shiftfast, they continue to help me every time I have a question or concerns I know I can reach out to them for help.

Best performance shop around for GM and subaru

Great shop with a very friendly and knowledgeable staff. They took the time to answer all my questions I had. I would recommend this ship to anyone in the Charlotte area.

Shift Fast is a great shop building some of the fastest cars in Charlotte. JR Junior Barrios tunes with them, and he was able to re-tune my car to gain a full 82 whp more than previous tune. This tune was tested on the track and ran great with no overheating issues at all. They also do great wrenching at a rate you cant beat, plus no service tax in SC! Owner Stewart has always been there for me and shop manager James responds quickly to any question.

I needed somewhere (besides the dealership) to take my Subaru after the warranty expired and had read good reviews about Shift Fast so I gave them a try. The check engine light came on one day so I called and asked when I could get them to look at my car. They said a week from tomorrow so I patiently waited, not know what was wrong with my car, and brought it to them the following week. They told me about their drop box so I could leave my key if I had to drop the car before they opened. When I spoke with them on the phone I gave them the full layout of my situation including the make, model, year, and color of the car and all my information and when I would be bringing it in. I dropped the car off and put my keys in the drop box and waited. I hadnt heard anything before 5 that day so I gave them a call. Turns out they hadnt even thought about looking at it they didnt know anything about the car or why it was there. So I waited two more days, calling at the end of each day to see if any progress was made. I was told each time well call once we look at it and wouldnt provide any kind of timeline as to when that might be. Finally on day three they looked at it and determined it to be a sensor in the catalytic converter. I had to pick my car up for the weekend and had to bring it back the following week so they could finally fix it. Well, it wasnt long until the check engine light was back on. I called to see when I could bring it back and they said it would be 10+ days until they could get to it and advised me to take it elsewhere to have the code read. Sure enough, it was the same code. I called again this time leaving a message, which has not been returned. Apparently they have no interest in making it right. Im sure these guys are great at tuning cars (which is why I didnt give them one star) and they definitely know their stuff but if youre looking for a place to do regular car repairs, I recommend you look elsewhere.

From my first contact with Shift Fast I knew I was going to be taken care of. Stewart spent a good time at night after they closed to diagnose my cars ailments. Even though I told him multiple times to go home and enjoy dinner with his family. After finding the issue with my car, both Stew and James spent countless consultation hours to find the best most cost effective fix for my car. The turn around for the new engine build was so fast, it is unheard of. Now my car is back together and running great. There are a few electrical gremlins that are plaguing the car that are 100% unassociated with the work these guys did, and they have had me in the shop on a moments notice tinkering trying to find the issues, 100% free. They have a dedication to each and every customer that cannot be touched by any other local performance shops, and really strive to make sure every car that leaves their garage is operating the best way, if it is not they make sure it is. There is no better shop around for professionalism, speed, quality or customer service. No wonder the top engine manufacturer (IAG) and worlds best tuner ( JR TUNED) have chosen to partner with Shift Fast and no one else. If you are looking for work look no further than Shift Fast. There happy customer base speaks for itself.

Phenomenal work done here! They truly know their stuff and take the time to explain to you any doubt/questions you may have. I know my car is in good hands when I take it there.

Dave is the man! He should be named the real daddy Dave. Havent had a single problem after him and his guys got a hold of my car. 10/10

Ive had a few good sized projects completed by the techs at shift fast and each time the job was completed when they said it would be, for the amount quoted. 100% quality and honesty. I wouldnt go anywhere else. Reputation speaks volumes in that line of work and they deserve/have a great rep!

The work they do is great and worth the trip to go check them out. They will get you in there and out in a reasonable time. They do it right the first time so, you dont have any problems later. They are honest and the prices are great. Check them out and they also have a All Wheel drive Dyno...Check them out you wont be disappointed!

Um well uh nevermind Ill be shooting myself in the foot! They own the program rights to my truck so....

Its rare in this day and age to find a automotive performance shop (let alone any business) that offers exceptional customer service by experienced and knowledgeable staff. Ive used Shift Fast for my Evo since they opened and the quality of the labor, fair prices, and overall attention to detail is simply unsurpassed by any other shop Ive used (and Ive used MANY). I recommend them 5 stars without hesitation.

Nothing but good things to say about the work performed at this shop. From tunes to oil changes to complete builds. Nobody comes close to the knowledge and skill of these guys. If you want quality, this is the place. I wont take my STI anywhere else.

These guys really know what they are doing. The third performance garage I brought my WRX to and finally everything that was screwed up by Mannys tuning and Redemption Racing and Garage has been set right.

Awesome shop with great guys

I definitely have found my new mechanic! The shop really impresses me with great staffs that are very friendly and confident. The thing that I love about it is the owner (Khank) and the technician (Stewart) who explains to me exactly what went wrong with my Lexus and went into detail when I questioned them. The prices are very reasonable but the most important thing is they were very courteous to me, were not at all pressuring me to get the service, and the number ONE thing - my Lexus is fixed and running GREAT!!! Thank you Shift Fast for the great service and I will certainly mention you all to all I know!

Staff was super friendly and respectful. I needed headers put on my car and they were competitively priced and they got the job done in a timely manner. I was very satisfied with the work they did.

Awesome place. If your project is almost there, shiftfast is the place to get it finalize. Got my car check and tune and came out extremely happy. Thanks so much guys for always answering all my annoying questions. Ya the best

Stewart and Shift Fast Motorsports is an amazing shop! I wont let anyone do anything to my vehicles except for them. They have always done a great job! They are being harassed from someone, and a lot of the reviews (negative ones) arent accurate or true. Thanks yall for doing a great job, keep it up!!

Cant wait to see what my STI does on the dyno! Knowledgeable staff!!!

These guys are the best! So helpful and great work! Highly recommend!

These guys are awesome, went in for a consultation for an exhaust modification, they knew exactly what could be done. Their customer service is AWESOME, and their shop is nicely setup. I cant wait to do some dynoing in the future!

No matter what size problem big or small these guys will get it taken care of. Thanks for keeping my cars running perfect

Great place! Stewart and the gang know what their doing and have great customer service. Highly recommended!!

Shiftfast has always taken care of me and went the extra mile even when it wasnt necessary. Id recommend there shop to anyone. They take care of everything from routine maintenance to full blown racecars. Id give em 10 stars if I could. Best in the business

Great shop with great people. always willing to go out of their way to make you feel welcome and informed. very professional way about doing business.

Stewart is the hardest working dude I know and his shop is the only one I trust to work on my Evo. Forever a customer.

Great guys I have used them on many occasions and none of my vehicles are 4 cylinder race cars and they do a great job at reasonable rates

I came across this shop via friends almost 4 years ago. Little did I know that Id feel like a part of their family from then on. By far the most humble, down to earth, friendly shop I have ever dealt with. From the start it was simply diagnosing a funny noise on a previous vehicle of mine, that later turned into regular service, dyno runs and exhaust work. Then onto my current vehicle, which I have ONLY they have touched. The guys there helped me go through the entire car and find things the previous owner hid. We went through the bolt-ons stage, which they did very well with. Quoting realistic prices, time of completion and power outcome. They have even offered me to drive their personal vehicle while mine was being serviced! Who does that anymore?! We did full transmission builds, and 2 years later we went through a full engine build. Never have I doubted the quality of workmanship or service this shop provides. From start to finish I was always comfortable leaving my vehicle in their hands. As I move onto my next vehicle in the near future, I cant wait to see what the masterminds at ShiftFast Motorsports can come up with next. I have found my shop for life. Keep up the great work guys, You Rock!

I was very nervous about getting my car tuned after the new setup but after doing research it seemed pretty clear. They did an awesome job and made me feel at home.

This is absolutely the worst place you could take your car completely unprofessional and doesnt have a clue what they are doing save yourself a lot of time and money and go somewhere else. In response to the lies below most places do a 93 tune and a race gas tune thats what you were paid to do. I asked these morons to vent the valve cover before doing any tuning they claim they cant weld magnesium Only an idiot would even consider doing that . Theres a huge thread on evom showing how to vent it without any welding at all I asked them to read it.... We all know how that ended dont we....... Threats of violence? Please .... You realize I can sue you for lying its called libel?

The best place in the southeast period to have you Subaru worked on.

I literally cant say enough good things about these guys. They can be queued up pretty heavily on dyno time because JR is the best of the best so make an appointment and plan ahead if possible. But its just another testament to the great customer service and workmanship, everyone wants their work done here and thats why theres a wait. My vehicle went down unexpectedly so I had to jump in line. James tolerated my 1,000 questions and walked me through every step of the work they did to my 2008 STi with constant updates. Every time I put my foot down I cant stop smiling. You simply cannot go wrong with Shift Fast, thanks guys!

GREAT PLACE LOVE THE SERVICE THE ONLY PLACE I WILL TAKE MY BMW THE SHOW OWNER IS DOWN TO EARTH THE WHOLE CREW IS TOP SHELF GREAT GUYS GREAT PLACE

Ive had multiple cars worked on at Shift Fast. The employees are very friendly, and the work is flawless.

These guys are awesome. They do great work and are affordable.

Best AWD Performance shop in the South East!Just because you might only see Evos/Stis doesnt mean they dont work on your vehicle with a killer price and amazing work

Great people. Great work. Amazing cars.

These guys go out of there way to be mean that customers that dont play their game. Dont buy into the lies and deceit. Youve been warned!

Pretty awesome people. Very helpful and nice.

Shift Fast has gave my car and me the attention no other shop locally can ever do. I took my car to 2 other local shops for service and maintance on my car and Shift Fast ended up fixin the mistakes done to my car from day 1 they took my car in have always had hard to beat prices and amazin service and quality work they worked with me step by step after my motor blew and rebuilt my motor and my motor has been runnin for 2 years strong better than before and every time i get in the driver seat and crank it up im reminded why i chose Shift Fast also once you get to met Stew he treats you like one of his own and makes sure he doesnt fail you no matter what and always puts his customers 1st and not to mention Shift Fast collabs with JR Tuned, Jrs tune are night to day differences if you dont know much about him youtube his name and see all the records he has under his belt and how many cars he tunes to perform the best they can, they will continue to have my loyalty and will be the only ones to ever touch my car period.

Top notch and the best hands down. Wouldnt recommend anyone other than them in our area.

Stewart is absolutely one of the best you can deal with. If you have an Evo, GTR, STi, WRX, Supra, Z, or any other hot ride and you want to make it fast they are the go to shop. If you want an honest repair shop Shift Fast is the shop to go to. If you need your car tuned they have the best tuner in the world with JRTUNED who comes out to personally make sure you get the best tune money can buy. Shift Fast is the only shop in the area to consider when you want to go fast.

Shop doesnt deserve anything less than a 5/5. Sad that people feel the need to leave negative reviews with fake accounts, but they must be doing something right to warrant that response from other shops!

Cool guy that owns the shop. I know they build some quick evos when theyre able to take a Tesla down.

Best service in town priced fairly

Totally love this Shop, So giving Shift fast a 10 for the Best Customer Service, great people, amazing job, fast on repairs, and high quality of work... Before the moment I was going to tow my car to Shift Fast Motorsport, I call them and they say before I tow it and waste money, they offer me to see if it was ok for them to come and see what the problem is before towing. Wow thats what i call excellent service :), Like common what other shops would do that? definitely not other shops, and dealerships... BTW as far as figuring out what the problem is, you guys (Shift Fast) managed to find out what the problem was right away and start the very next day on it...Your price was way less than the other quote Ive got before. Which is VERY good!... Save a lot of money- thank youI could go on and on but I dont want to obligate you guys to the excellent service you gave me. All I can say is that Im a Satisfy customer... And my baby have found his mate :).... Moreover i will want to recommend this shop to others out there, not just Performance cars, but every car that needs help, so why wait when you have a shop that you can trust?Thanks A lot to:-Khank N-Steward-and your technicians

Hands down the best performance shop in the area

Great automotive place

Good guys to work with.

Honest and straight forward!

They lied

Reliable
