Gonna say this loud and proud and I beleive I speak on behalf of all shops. If we work on your car and theres an issue, it doesnt matter if its been 1 day or 1 year, we need to be notified first and it needs to come here if you expect us to see whats going on and make it right. The second another person or shop touches it, our hands are washed. No one can fix something they dont know about. And no you bolt on LT1 isn't gonna make 600wheel.

Miata in for a quick alignment this morning! Need an alignment? Call or message us to get you on schedule.

Our first big GTR build is back on the streets. It came to us in pieces and a blown engine. Went through the whole car pretty much. Now has a built engine, single turbo setup, full fuel system front to back, and all the haltech goodies. Customer supplied the turbo and manifold so we made what we could with it. Ended around 475whp. In the future we might upgrade those and then turn it up to 600! Also got some gram light nismo wheels wrapped in Michelins and put the on and that changed the entire look of the car. Sounds good, runs good, and drives good.
