Highly recommend! Mike and Ryan are both very knowledgeable and experienced mechanics, with a passion and niche for high performance. The shop runs on schedule and all work is done right the first time. Plus, they called periodically to give me updates, lay out different options to solve specific problems, and guided me on the best solution for my car, my needs, and my budget. Oh, and upon inspection they also found additional things that needed to be fixed now or in the near future. All of this gives me confidence and I know that they take pride in ensuring cars are running their best. It can be hard to trust someone with a prized possession, but theyve earned my business and trust on my 1965 Chevy Nova (twin turbod and approx. 900 HP!).

Will be taking car to them in a week or two. They have awnsered all my questions about the build and wiring problem im having with a no start. Thank you 5250 performance.

Very poor customer service. After trying to contact multiple times via e-mail and calls, unless you are planning on dropping big money, they want nothing to do with you. Happily taking my cash somewhere else (8/17)Update in reply to owner : I was contacted on 8/4/20 by Michael so thats incorrect. Dont worry about following up however, Ive taken my business elsewhere

Big shout out to mike for taking the time to help with my evo 9 to pass emissions!!!

Very good service and foresight into the future.

Mike is awesome. One of the only shops to actually write me back and invite me in to just see their facility. Really appreciate the great service. I highly recommend 5250 Preformance.

Top notch shop and very knowledgeable! Anything you need done to your performance car I’d go here. Brought my 2006 LGT in to get a cat put in my down pipe. No performance lost and can pass emissions now. Great shop, good people, quality work!

Great knowledgeable staff. Absolutely recommend

I contacted 5250 Performance about doing a custom install of a small turbocharger on a diesel ATV after having trouble finding a shop interested in taking on such a job. They ended up fabricating a stainless header and aluminum piping on the compressor side, all of which fit nicely within the tight confines of the ATV frame. Overall, a nice, clean job at a reasonable price and that works as intended. Highly recommended.

I have always had nothing but the best experiences with Mike and his crew. Mike has been my go-to mechanic for any task big or small, he is extremely knowledgeable on all platforms. You can tell every car he touches, he takes as much pride as he would in his own vehicle. Every service he has done for me has been done with extreme precision and you can tell the job was not rushed. Mike pays attention to details and gets whatever you need done right the first time!I look forward to doing a lot more business with Mike @ 5250 Performance and will continue to recommend his services to everyone I know.Thanks again for everything Mike!

I had a tow hitch installed on my Tesla Model 3 and Mike was great! Mike was very professional and did the install in under 2 hours and 5250 had the best price in the area!

Poor customer service after their failure to complete the repair properly. Literally left me stranded and on my own to tow my car home after a sensor was left partially unplugged which should have been caught on the test drive. After contacting Mike he offered a small discount for future work?! I only asked for the tow bill reimbursement. Totally unsatisfied and will not be returning.

Happy with the service! I had a few anxieties about the health of my car and Mike and crew did a great job and took great care of my Subaru! Made some adjustments that really helped with drivability. I appreciate that this shop is honest and upfront about the work performed or going to be.

I worked with Mike and he was super helpful and above all else, friendly. He was willing to help with any direction I chose to go and gave me a sweet deal on an HKS cat back exhaust. Amazing customer service.

Excellent shop. for anything big I only use Mike at 5250 Performance for work on my 2012 STI. One of the few shops that I have encountered that can take some of the biggest builds from start to finish with the craftsmanship and professionalism demanded by such large budget projects. Quick turn around times and very methodical/knowledgeable approach to everything this shop touches.

Great, knowledgeable service. Quick turnaround. Very pleased overall. Would recommend to everyone, and will be a repeat customer.

Mike does it again with some awesome work. One of my pistons blew itself apart and I brought my 2010 STI up to Mike to take apart the motor. Everything was a complete loss. So I decided to build it up. Mike put in an IAG short block and fabricated a rotated kit along with a bunch of other parts. Work that he did is great and he communicated with me constantly on the entire build. If you want a build done correctly the first time go to 5250 Performance. They do anything from maintenance to high horsepower builds. Great customer service and treat your vehicle like it is their own.

Mike was awesome to deal with. Very knowledgeable and saved me 1500 bucks not having to deal with a dealership. Would highly recommend.

Mike is the best, if you have a Subaru you should be getting it fixed here. Honest, fair prices and good quality of work. Highly recommended.

Great shop!!! Highly recommend!!!

I attended a dyno day at 5250 and about halfway through one of their ramps broke. Instead of giving up, they were able to use what they had left and get everyone else through. Very impressed!

Mike has helped me alot since Ive gotten into modifying my Subaru BRZ I will not take my car anywhere else but here they are honest knowledgeable mechanics.

I took my 2009 Subaru WRX here to have the dreaded firewall spot welds fixed. I was recommended to come here by a local Subaru Performance shop and was happy to know 5250 has fixed the issue plenty of times before! Mike was super helpful and knowledgeable in explaining the whole process! They had it done the same day, now with having my car back and driving, my anxiety about the welds has been relieved. The cars clutch pedal has never felt better and the shifting of gears is restored to a smooth transition! I would 100% recommend you take your 08-14 WRX or STI here to have this issue fixed! Thanks for the awesome work guys!

Nobody answers the shop phone or returns calls.

Have an 09 WRX with the dreaded firewall issue and squeaky clutch pedal. Had it fixed by my now ex-mechanic, but that failed within 3 weeks of the fix...My old mechanic essentially gave up and said to get rid of the vehicle. Found 5250, talk to Mike and he was very knowledgeable and straightforward with the issue of the firewall. He helped me walk through some areas of where the prior repair failed. Brought the vehicle in and they were able to repair the firewall and found another area in the pedal assembly that was the culprit of the terrible squeak. It has been nearly 1 month and my car has never felt better while driving. He provided me with pictures of the old repair and the changes he did.Would highly recommend Mike and 5250. Though out of the way up in Longmont, still worth it.

Over the weekend I sent an online request in. Mike called me back Monday and diagnosed the issue over the phone. Excellent customer service.

I would not let anyone step foot in this scam shop. I can believe it still runs i took my car to get dyno tuned by the owner, he tells me my car has a blown head gasket after running his diagnostic. he blew my brand new radiator and had fasley accused me of hot riding my car to just find out it was just a blown water pump and engine was fine. i spent over 2gs because of 5250. if i were you dont come here all he did was argue with me maybe thats why now 1 year later his hair is gone karma does exist.

I have a 700rwhp corvette that i could not get to pass emissions. Also had a bent procharger impeller. Mike said he had the answer. I already had high flow cats on and was really skeptical that the cats that Mike wanted to put on would work as well as he said they would. Took the car over Mike got the cats on right away and sent the procharger to procharger since they do not sell parts. As soon as the blower got back from the rebuild Mike had it on same day and the car was ready to be picked up. Took it to the smog station and it passed with no issues. Before and after pics of the smog are uploaded. I can not say how happy I am with the work and service I got from Mike. Will be taking all future work to him!

Highly Recommend this repairer. I have had two specific jobs done there so far for my 08 WRX:Fixed Pedal Assembly Bracket Bad welds (Modded to 7 bolt solution)Install of Grimmspeed UpPipeMike is super friendly and knows these cars well (Their Known issues). Let me know what else might be on the horizon for this car so I ca keep an eye on it and plan for it.I am taking my car 60+ miles to specifcally get this repairer to do the work !!! I trust them.

Mike is great with performance issues and diagnosis. I had a great experience with Mike and 5250 when I took my Supra to him for a list of stuff my car needed.Mike is helpful in doing what was needed and also making suggestions as to what would be next and how to get there. Mike works seamlessly with Tuner THE BOOST CREEPand that is an asset to working with Mike and 5250.Thanks for everthing and love the new location!christian-1989 SUPRA W/ 2JZ-GTE SWAP AND AEM STAND ALONE-400 HP/400 LB FEET OF TORQUE

I came in there today to get my Grimmspeed EBCS installed. COULD NOT be more satisfied with the work. Mike is a really great guy and I will ALWAYS big coming back to him for amy install work I need. In addition to my install he also rethreaded my intercooler and BPV, Fixed my intercooler housing and sealed everything. Cannot write enough great stuff about this place! I live in Littleton and let me say it was well worth the drive coming here. HUGE thanks to Mike and if I could rate this higher than five stars I would!!!

Highly recommend
