We go the extra mile to deliver the best customer service, quality products and workmanship for every vehicle. We treat your car as if it were our own (and we’re pretty neurotic about taking care of them).

I first met John when he was a mechanic at Cobb Tuning SoCal. He worked on porting my turbo because my 2012 STI has some boost creep after a pro-tune.

Fast forward a few years later, I went back to him for a turbo inlet hose and anti-lift kit install because of the outstanding job he did while at Cobb. The level of attention to detail is amazing! During the install of the anti-lift kit, he noticed some imperfections in the kit (brand new, unopened). He showed me exactly where they are (it happened to be on both sides, same location, possibly during manufacturing), but they were slight.

The car drives fantastic and the work he does definitely shows. You can’t go wrong with Corner Speed Tuning. I’m definitely going back in a few months for more installs.

So the owner of this shop, John, has been a real good buddy of mine for many years. Met him early on when i got into the Subaru scene and has helped lead me in the right direction when it came to my build. Super knowledgeable and one of the friendliest people you will ever meet.

No question is too dumb for him, he will answer any and ALL questions in a way that you will full understand. His work is another fine thing, he is extremely meticulous and careful when it comes to his work. He is fine example of how all shops should be. He has been working for his own shop for a long time and I’m really glad to see him achieve it finally!! I would recommend this shop to anyone and everyone!!! Look forward to coming back in the near future!!

As a girl, I have a consistent habit of not trusting the majority of men when it comes to buying or building my car in a certain way. As soon as the WRX came into the picture, everyone had something to say about what to do and how to go about it.

John earned my trust as a builder and mechanic based on his own road racing experience and in-depth knowledge of several platforms. I hugely appreciate his honesty, suggesting a build project with products that easily adapt to my needs and goals, as well as talking to me as a fellow driver, not a “girl.” He maintains his integrity and emphasis on quality workmanship, which is second to none.

My racing season starts next weekend. It’s an awesome feeling to have a car that’s nicely sorted out for my level of driving and will continue to evolve with me.

My WRX will be a regular customer at Corner Speed Tuning, from general maintenance to the ongoing race car evolution.
