Mr P, that seems to be the story when running a 4spd. With the et radials anything above 2800 rpm just spins the tires no matter how little pressure I try. Again I am not in the same league as most of you and just want something that will be a little forgiving with my inexperiance at the track. That is what is so great about this site all of the guys helping everyone out even when they ask dumb questions that have been asked many times in the past.
