Found these guys on Craigslist and thought I would check them out and see if they were legit. After speaking with Carlos I was confident that this wasn't a bogus business. I met with him and turns out I had purchased the wrong gear set for my car. A week Later I returned with the right years but still insisted that he try to put the original gears that I purchased in because it was a more desirable ratio, He went above and beyond trying to make my high rate ratio work just to make me happy and prove to me that it wouldn't actually work my bad sorry Carlos he ended up spending twice as long and what was needed just to make me happyThe car runs great and I honestly can't speak highly enough about Carlos and his team
