Company Profile
C-YA Racing started about 6 years ago with a problem. I had just blown my 2nd transmission in my new 97 Pontiac Grand Prix GTP. It seems I have found ways to make enough power that the stock tranny just wouldn't hold. One wheel burnouts were killing me and there just had to be something I could do about it. After many try's and lots of broken parts, The C-YA Racing LSD was born. Now after selling them for 2 years with very good results. I have been able to take on several other projects. See the Products pages for all the other things I've got going on as of now.

All C-YA Racing parts have been developed and tested on the track as well as the street before I even put them in anyone else's car. If the 12.2 second street driven "Pit Bull" can't break it, I think it will last in most anyone's car.
