Well I just ruined my 2nd centerforce DF so its time to try something new. Car is a 89, tremec 3550(10 spline), h/c/i s trim 475 rwhp at 92 degrees. I was really looking into the astro stage 3 setup, very reasonably priced and can handle 600 hp. Ive heard mixed reviews about spec, and some good things about RAM 900 series. Car will prob only be at the track afew times a year but will see 5500+ launches, but still hooks hard on the street. Also need to figure out something for a flywheel because I think that also have something to do with my problem, looking for a billet steel just not sure what brand. Stock bottom end so 50 oz is needed. Thanks.
