I was going to take a speed controler out of one of my TC's and was not sure what one I should use,I also have a V12 GM,I was running an LRP 7.1 in my 12L3 but it is a bit on the big side and I wanted to down size my radio gear on my CRC,The track I race at all they run is stock,heck I cant even talk anyone into running 19 turn..
I was even thinking about using an LRP sport..just not to sure on that one.
