This shop is the Best in So.Cal that I have come across..... Being a "Car Girl" it is hard to find a place that doesn't try to get one over on ya but this shop is honest and they do quality work at a fair price. They have a comfortable waiting room and a very clean shop. I highly recommend GTR for all your car needs...you won't be disappointed

I have a 2006 Mustang GT that I had GTR put a Kenne Bell Stage I along with suspension upgrades. Ran great for seven years not an issue. Finally decided to rebuild the engine instead of putting in a new Coyote motor/ transmission unit. Gonzalo gave me the recommendation to rebuild the stock motor and keep the transmission I already had that had just been rebuilt. Took them over six months to even pull the engine out of the car. Took them from March to August to get the engine back into the car and running to any degree. Shipped the car back twice to fix the new engine for the same issues and It is still not fixed. I m stuck in Albuquerque with surging in low idle speed to the point it pulls through the brakes, stutters at highway speeds like there is a clogged fuel injector and no one can figure out how to fix it. It took them two years to rebuild a motor that still doesn t work. I have a email trail that is two years long dealing with the promises and excuses. I wouldn t recommend them for anything at this point. I have spent close to $20,000 to rebuild the engine that doesn t work and wasted two years with the vehicle at their shop almost the entire time. Not sure what the issues are but it is not the same shop that put in the Stage I.

Best shop around if you drive a mustang had my 16 GT pushing 700hp comfortably. But plan in advance them being the best means they are always busy and you re gonna have to schedule something, but worth the wait.

The staff was very kind and helpful, especially Gonzalo. Service was excellent, and they managed to squeeze me in with an appointment despite Covid staffing and all of the other work from other customers. They are very knowledgeable and definitely know what they are talking about. I would definitely recommend anybody within a second.

This place is very knowledgeable and helpful. I had Ricardo dyno my car car today and he kept me informed thru the progress and readings. He explained key elements we were looking for with air-fuel ratio, power, and torque. Highly recommend this place.

Hands down the best shop in CA. Covid kind of screwed me with timing and parts on back order but as soon as everything was in, it took them 4-5 days for a motor drop with a KB supercharger install. Couldn t be anymore excited and definitely will be with these guys in the future, THANK YOU GTR!

Just picked up my ride today from GTR high performance, and I must say when I dropped it off I was a bit worried about the outcome. In the end, she runs better than she ever has before.i don't know what kind of magic they did but you can tell and feel the difference. A huge shout out to Ricardo for taking the time to explain to me everything that they were doing to find the issue with my car. Like always you guys kick ass!! See you guys soon for more goodies!!

Honest people. Very knowledgeable people. Ricardo and Gonzalo worked on my 1991 Crown Victoria and 2016 Mustang GT. Very satisfied with their work and way they conduct their biz.

So after this diagnosed from GTR I kinda gave up on my car thinking that the misfire could have been a major internal problem . Since I didn't get a straight answer. Left car sitting for almost a year . One day I decided to install a new set of wires and my problem was solved . Took it in for a DIAGNOSIS !!! Why didn't you guys try a new set of wires??? Having so many mustangs in the shop they could of tested a new set of wires instead of assuming that my brand new injectors came out deffective . I gave summit hell because you guys said my injectors were the wrong ones being aftermarket. Two people highly recommended me to ur shop . So dissatisfied.

I took my 93 Mustang for a restoration and upon pick up after Minor work, my wheel came off because they didn't remember to put the lug nuts back on. Unbeleivable!! A health Hazzard and poor work that could have resulted in physical harm to me and the general public.
