Circuit Motorsports

Brought my 2020 WRX in for a tune and to replace my header manifold gaskets. During inspection and leak down test they found multiple leaks from my exhaust up to my turbo. Tristan was quick to get back to me about the repairs needed done and after I let him know to do them they were super quick to have everything done. Got a new downpipe and 3 port boost controller through them and the money it costs to get things installed through them is worth it! They got my car up and running amazing and the tune has made my car run smoother than the day I bought it. Thank you CMS!

Beware Raptor owners! This is not for timid drivers, or just cars, these people can really beef up your truck as well. They sent me pics of their work, which is awesome, but also said exactly what they would do and how much it would cost up front.. Nice to do business with people that have the knowledge, integrity, and patience to walk me through the whole process. It's nice to finally have someone trustworthy to work on my baby. Tristan, thank you my man, my truck runs awesome and I will be back to get other stuff done. I'm excited for the next project, Cobb intercooler and tuner installed on my truck.

I've been here a couple times now with my 2011 STI. They have always done a stellar job, their work is top notch, they are friendly and knowledgeable, and my latest tune feels amazingly good.

If you need some work done and/or a new or updated tune, fear not. Circuit Motorsports will sort you out good and proper. 👍

When Subaru informed me that I blew a head gasket on my 2019 Crosstrek, I was left deeply frustrated until my son put me in touch with Circuit Motorsports. Tristan and his crew were professional, upfront, honest, and great to work with. Although there were some issues that arose that were completely out of their control, Tristan kept me up to date and honored his estimate. I would not hesitate to recommend Circuit Motorsports to anyone who needs a performance auto shop. Thank you Circuit Motorsports!

I highly Recommend Circuit Motorsports. I have been working with Tristen and found him to be very friendly, knowledgeable, and professional. I’ve had everything from a short shifter and Cobb Access port install all the way to a full white line suspension install. The work has been impeccable. I’m looking forward to the next steps as they take my WRX to the next performance level.

I wholeheartedly recommend CMS. I just wanted to do a review of Circuit Motorsports as they have done extensive work to my car to the point you wouldn’t recognize it if it wasn’t for the bright Sonic Yellow. The details that people would never see at first glance if ever but makes it even more functional and unique. My 400hp engine build you did is three years old now, time flies, it’s never leaked a drop oil and it wouldn’t be to healthy but that powder coated intake manifold is still clean enough to eat off it. I know it’s my car and we all think our cars are special but I’ve had this car for 6 years it was nothing but bad luck until I brought my car to Circuit Motorsports. The engine blew 2 days after I bought it. Shop I took it to parked it under another car every night the car was there caustic fluid leaked from that car destroying the paint on my hood hence the carbon fiber hood. They installed a radiator but left all the 100k mile clamps that slowly leaked causing the car to overheat. After that fiasco I looked for another Subie shop to tune my car and there were two big ones. The first didn’t even give me the time of day. Circuit went through everything and found that the compression was bad in every cylinder. So they put together a rather extensive hybrid build using Hybrid JE FSR pistons to solve the normal hybrid hurdles. They suggested things that were necessary and worked with me informing me every step of the way. Did the dual ball bearing Blouch 18g that spoils damn near stock but doesn’t fall on its face. The custom position of the IAG air oil separator and the Cobb BPV are so neatly done you’d think TurboXS designed the piping to go like that. I was lucky to get JDM MY00 STI 5 speed gears that were heat treated and shot peened and put in a 20004 case. They went through it changed fluids and inspected it from front to back and replaced worn pieces. They also added Moore blast plates for some added security. But I still don’t trust launching any 5-speed. Being that as it may I asked them to limit power to just 375whp to preserve my transmission until I get a real six speed. I got 374whp and 383wlb/ft torque. Stew from Rogue Tuning did an excellent job not just getting power but the part throttle and drivability is near perfect and I’ve had some high hp cars. I also have an AEM water methanol MAP based system installed in my car. Several tuners didn’t even want to touch it he tuned the hell out that car and it rips Stew’s words 😆. Which is more than enough power to enjoy nice country drives. I never take my car anywhere else to get work done even oil changes. It’s been a while since my build was done but I wanted to see the results over time before I wrote a review. I’m not sponsored or anything I just spent a good amount of my hard earned money building my car and I respect the good work that they have done to my car for a fair price So if you got a Subaru and let’s face it they can be temperamental if ya don’t treat em right and they most certainly did. I included some pictures of what it was and what it is now.

5 Star review for these folks! 2016 Mustang tuned and it’s amazing! Thank you for the opportunity to run this turbo @ 325 HP!

I started this project because I like to build things. My first subi and knowing nothing about them, I ordered the parts and started tackling the project. Once finished I drove 6 hours to Circuit Motorsports. These guys did a pre tune Inspection. Found multiple things I did wrong. They got them fixed. Changed out the plugs and put it on the Dyno. We made 426 whp. Going back soon to get flex fuel, bigger injectors and another tune. Thanks guys! Would highly recommend them to anyone.

Circuit Motorsports installed a new CX Racing front-mount intercooler on my 2015 Kia Optima SX turbo. They did an excellent job! I couldn’t be more pleased with their professionalism, workmanship and attention to detail. They had to make some modifications to my vehicle to get the FMIC to fit correctly and did a great job making everything work properly. Tristan was extremely professional, knowledgable and great to work with. He and his team completed the install the same day. I highly recommend this shop and will be returning again soon!

I went in for a pretune inspection, smoke test and dyno tune for my 2019 Subaru WRX. Tristan the owner was very professional and really knew his stuff, they took great care of my car and I'm very impressed on the outcome of the tune as well. Circuit Motorsports goes above and beyond over what the dealership provides. 100/100 I'll keep going here to get my car needs taken care of.

Had an issue with my turbo BRZ. They were able to run diagnostic tests, find the problem, acquire parts needed and solve the problem, all in one day while I waited in their lounge. So yea I'd recommend this place!

Brought my Cobb Stage 1+ 2020 WRX in to have a J-pipe installed and get pro-tuned. It was more expensive than if I had done it all myself, but completely worth it! They recommended a high-quality ETS GESi catted j-pipe which was definitely worth it. No CELs from O2 sensors since the GESi cat has a higher cell count than what other aftermarket j-pipe manufacturers generally use. They did a pre-tune inspection to ensure the car was in working order to prevent issues from occurring on the dyno, then the tuner tuned the car! The car reliably made much more HP and TQ than I was expecting, and I’m very satisfied with how it drives! There is no rev hang, running less boost than stock (more reliable), no CEL from O2 sensors (better emissions compliance), and a much more race-inspired exhaust note (ETS GESi catted j-pipe + Invidia N1 Dual catback). At low RPM (<3000 RPM) I am achieving comparable (possibly slightly better) MPG than on a Cobb Stage 1+ OTS map, while also making SIGNIFICANTLY more power. I was provided with my dyno graph, a list of tips and precautions for tuned engines, and suggestions for supporting mods and maintenance to help keep the engine running long.

Circuit Motorsports is a top notch quality motorsports establishment. Their work is excellent and the prices are fair.

I don't have much space at my residence so I had a bunch of parts shipped directly to them. Not only were they willing to accept it but they were willing to hold on to it for a few months until I had time to bring my car in. The install by their amazing technicians went flawlessly and then I had their Ecutek Master Tuner do a protune on the dyno as the final step.

Everything went so smooth. Special shoutouts to Paul (who has since moved on to another occupation) and Alberto and the rest of the Circuit Motorsports team for an amazing job getting my Subie taken care of. Cheers.

Couldn’t speak more highly of everyone at Circuit Motorsports! I took my car in for a plethora of upgrades, including a big turbo, and they made this car something that I am so damn happy with. I received messages every day til it was done, keeping me up to date with progress and voicing any concerns they had. Will be going back for any and all future builds I have!

Took my 2021WRX into Circuit Motorsports to add some performance parts and on the Dyno for a tune and they came through with flying colors! car has been on the track with zero issues. Can’t wait to put on more parts and more track time!!!!

I just want to say that I’ve always had a wonderful experience here. Tristan has always been kind and willing to talk about the build or answer any questions I had for him.

I called him about my new-to-me 2000 Impreza RS, he didn’t hesitate to have me bring it in so we could look over everything. They did a full refresh, because the car needed a lot of love, and I couldn’t be happier!

Circuit Motorsports did an excellent job on my Scion FRS. Had problem with the throwout bearing and was upgraded to the new clutch. The price was better than other estimates and we include upgrades parts. Definitely recommended. 10/10

They installed my lowering springs on my 2018 WRX. 100% recommend for having aftermarket parts installed or if you need a tune go here. Quick and easy to work with them as well.

Great shop, great work. I contacted circuit Motorsports as I have been following them for a long time on Facebook since buying my sti back in 2015. It was time for breaks and they did not disappoint. They were very busy and were able to squeeze my car in even when I had to cancel a day due to my new born arriving! 100% going back. Thank you guys

Went here first to get an exhaust installed, went perfect.
Then I went here to get headers installed, went fabulously.
Today I went here to get my clutch replaced, my car is now a completely different beast.
You get what you pay for here and prices are absolutely reasonable.
I will always stand by Circuit and their work, so thank you Tristan and your team always! You guys are very much appreciated.
