Always come to this site. Never fails and very attentive. They always answer all my questions and emails. Great service. 5 stars

Harold provides you every services you need for your performance cars! He recommended MCS dampers for my C6 Z06 Corvette and it is worth every penny! It changes good handling car to even better handling car. Harold is a good man you can trust for anything from general maintenance & repair to tuning & modding your car.

I was in the process of getting turbos installed into my car and Harold at HP was the only shop who accepted the job. Glad he did, had a great experience with Harold and the project he did for me. He even took the time to help me with additional work aside the install itself and made sure I was 100% satisfied and the car was running at its best. This was about a 3 day job but due to fault of MY kit of missing hoses and other miscellaneous items, the job took about 4 weeks and Harold didnt mind at all, he made sure the job would be done properly. I am a returning customer and will only go to HP to get installs done. Aside my kit he also installed a fuel system and other supporting parts for my car. He does great work and fast turn around. Also responds quickly to emails and/or calls. Thanks Harold and HP Autosport for you work!!!

Went to HP Autosport for my first service on my Lexus IS200t. It was quick, easy and painless. My car only has 5000 miles on it and I know it shouldn’t need anything other than an oil change. That is all it was done and no one try to sell me anything I didn’t need. It’s hard to find a shop like this one these days.

Irie Roots Service came help no problems. Had what I and I needed. If want your car/truck done with LOVE .H.P. IS THE SPOT. EASTSIDE ROOTS RASTAFRAI S.B ✊🇪🇹OLD SCHOOL 🔥🌲

Great experience. Needed track brake pads for my M2 at the last minute, and placed the order just before Memorial Day weekend. Harold emailed to confirm the order and when it looked like the delivery date would not get the pads to me in time, he changed the shipping method to make sure they got to me before I headed to the track. Great email response over a holiday weekend! Delighted with the service I received. And the brake pads are great as well.

Harold and Team were great. They installed coilovers on my car and did great work. There was a missing part from the manufacturer and they were able to get one fabricated to ensure my car was completed on schedule. Highly recommended.

This place is amazing! Harold has been awesome, provided excellent service. I loved how he took his time and displayed vast knowledge on suspension tuning. It just made me very comfortable being able to leave my E92 M3 there for a an alignment and corner balance. The car has never felt better, and he gave me very good tips as to what I’ll need to do next to really dial her in. Took my car to autocross that weekend, and besides needing stickier tires, the cars itself handled excellently and I was very pleased! I will definitely be going here from now on for his services. Don’t waste your time at big brand or any of those other alignment shops. Just have Harold do it right the first time. Thanks again!

Ordered the sway bar links on their website and got a immediate response even though they were closed. Harold made sure that I ordered exactly what I needed and shipped them as soon as they reopened. I received them quickly and they fit perfectly. I would definitely use them again.

I have always had a fantastic experience when working with Harold and the HP Autosport team. They have extensive knowledge of repair and aftermarket parts, particularly for European cars. Harold has been a great resource for modifications on my BMW M3. I would not hesitate to recommend them as a trusted shop to maintain or modify your car.

High quality. Those are the two words that I associate when you say hp autosport. My foam drop in filter is three years old, still not one problem. When I emailed them with a question they were super helpful. Small businesses make America run!

Highly recommend!Harold has been servicing my cars for years. He is knowledgeable, honest, and very reasonable priced.Ive been ripped off in the past by other repair shops who recommend unnecessary services to pad their pocket, but I can always count on Harold to tell me exactly what needs to be fixed.The shop is also very clean and organized, which is a sign that he also takes care of the cars he services!

This company was great to work with. The web site was very clear before my purchase and during the waiting period the staff was helpful and polite with my inquiries.

Ive been going to HP ever since I purchased my current car for the most part. I made the mistake of going to the BMW dealership for my first couple of months owning the car. Then my friend referred me to Harold and through all of the regular maintenance, repairs and performance upgrades I could not be happier. Harold is very knowledgeable in his field and he will happily discuss and assist you in any way that he can. Though arguably on the pricier side I find that the work done at HP Autosport is well worth the price.

Harold has been extremely helpful over the years with all of my BMW racecar needs. Rush shipping, help deciding between different manufacturers for components... Great shop.

Very happy that Harold & crew worked on my 2005 Silverado. Great work and service! Highly recommend to other domestic vehicle owners. Thanks Harold!!!

HP AUTOSPORTS technicians and mechanics provide excellent quality service and repair for your cars regularly scheduled maintenance and also offer high performance tuning. Harold is an excellent experienced mechanic technician of performance cars. He can trouble shoot and fix most problems the dealers overlook.

I ordered some performance parts that HP had actually worked within the manufacturer on. Their knowledge of how the new components would work on my car was invaluable. They new components have exceeded my expectations.I knew the parts would be backordered. HP Autosport kept me up to date throughout and worked with the manufacturer to get my order ASAP and I got the order earlier than expected.

Harold and HP Autosport are awesome, just wish I lived closer! Even working remotely Harold offered sound advise and practical insight for my situation. When the new parts I needed were backordered he helped me source used parts at a great price and offered knowledge to get the job done correctly, highly recommended. Thank you!

I took my S85 here to get some modding and tuning done. Harold help me and gave me a lot of good advices! He is very knowledgable in his work and passion for what he does. Nothing can beat finding someone that has passion for his work. I will definitely come back again for all my BMW needs!

Top notch service and professional shop. They really took care of my car, went above and beyond with their work. They replaced my brakes and changed my oil, super impressed with the cleanliness of the work. I will definitely be going back for all my maintenance work.

Harold, thanks again for your assistance and professionalism in setting up my 528i suspension (H&R springs and Koni Struts and Shocks) and intake for my 540i. My go to guy for auto advice and recommendations. Thanks again for your professionalism and friendship all these years. 🤙🏼

Rented their E8x subframe bushing tool online. Website is odd to navigate, but the overall experience was easy and fast. Tool arrived quickly, and I had the job done within a day or two.

Great help and advice. Quick response on questions I had on suspension set up and product info.

Not cheap, but the parts are well made and worth the money. Purchased some tools for e90 bmw differential and saved me time and money because the tool was rugged and thought out. Customer service is prompt and informed.Well done HP autosport!

Friendly and knowledgeable. They took my car in and serviced it in a timely manner. I was on the road by the afternoon and the car runs better than ever! Its good to know you also carry BG products as I have used them for years. Thanks HP.

Had my Mustang GT oil changed at HP Autosport. Very clean and professional repair shop. Very efficient as well. Thanks guys!

Thanks to Harold and his team on taking care of the services and repairs on my Maserati Quattroporte and Audi Q5. They have always been very courteous and finish the job in a timely manner. I no longer have to driver over an hour to West Lake Maserati and that saves me lots of time and money.

First time into HP Autosport, Harold seems like a very smart and meticulous guy. I brought in a supercharged bmw for a tricky diagnosis. Will be going back, for Harolds expertise.

Found this shop through the Bimmerpost forums when I was looking for a new set of coilovers. Harold reached out to me and was able to advise me on a recommended setup with a fantastic price compared to competitors. Im done with upgrades for now, but I dont doubt Ill come back to them when Im ready for my next upgrade.

Order process was smooth, items shipped on time and arrived in good condition. Would buy from here again.

Easy to deal with and very helpful.Recommended A++

Always helpful in answering questions, they sell high quality suspension parts, and they have a great deal of experience they are willing to share.

HP Autosport was my go-to tuning shop for my BMW’s. Just about every mod was purchased from HP or Harold gave me advice. He turned my 1M into a track beast. Highly recommend Harold and HP Autosport.

I have taken my Subaru to HP Autosport for an oil change and brake service so far. They are efficient and very knowledgeable. They can do it all, from oil changes, brake service, repairs and maintenance. They not only work on Japanese cars but also specialize in Audi, BMW, Maserati, Mercedes, Mini, Porsche, and VW. I wont take my car anywhere else.

Harold at HP Autosport thoroughly answers my questions on the phone and via email providing me with his experienced insite on purchasing and/or repairing parts, best for my F82. His patience and knowledge is appreciated! (A dying breed of service anywhere today) Thank you Harold & HP Autosport!J. Jordan

Many modifications done in record time with exquisite attention to detail and nothing overlooked. This place is the real deal. Thanks, HP!

Incredible parts and customer service. Highly recommended!

Incredibly helpful staff, fantastic service. If you have an issues with your BMW, HP Autosport has a solution for you. If you need advice modifying you BMW, HP Autosport is your go too place. I’ve purchased countless items for my 1 series from HP Autosport and the service has always been fantastic.

HP has taken care of my BMW since i bought it 5 years ago. They can do it all, from performance parts, corner balance, repairs and maintance. Just recently they were able to track a boost leak, and fix it. I will be seeing them soon for a transmission flush. I wont take my car anywhere else.

Superb quality of products and genuinely brilliant customer service. Many thanks again!

Great service. Harold is extremely knowledgeable does really great work.

Friendly & professional - we were passing through Santa Barbara & they helped us with our VW Golf. It turned out that parts would take too long to fit in our schedule, and they communicated that immediately. Thanks!

HP Autosport has a great range of high end performance parts and the knowledge to back it up. Harald helped me plan a complicated Ohlins/Swift/Vorshlag suspension setup for my 1M bodied, S65 powered E82 and helped get the timing and shipping right for me to pick it all up while traveling to the US. Highly recommended.

Received my Slek Design Front carbon Lip for my BMW 1M and couldnt be happier. Shipping was also quick to Canada.

Fantastic Service. Harold is the best seller ever.

Super knowledgeable and helpful. Service is amazing - highly recommend HP Autowerks.

Harold and Chris are excellent at what they do! This becomes immediately apparent once you enter their shop, and see that all kinds of high end luxury and sports cars patiently awaiting for their top notch service. I brought my 2016 5.0 Mustang in, and had them do quite a few things to it including a few suspension mods, splitter install, as well as adding aerocatches to my brand new carbon-fiber hood. I was most concerned with the aeorcatches, seeing as two rather large holes had to be drilled into my brand new (and not cheap) hood. But my doubts and concerns immediately vanished when I went to pick my car up, as not only were the latches properly installed, they were also perfectly aligned. All of the other work was performed flawlessly and within a timely manner. Its very apparent that Harold and Chris love what they do, and are great at what they do. Although there are cheaper alternatives available when it comes to local shops, HP autosports is just proof yet again that you pay for what you get, and in this case it is top quality and friendly service. Im confident that theres very little that Harold and Chris cant do when it comes to working on cars. I will definitely be returning with any additional work that may need to be done to my car. - Nick (AmericanV8Guy)
