I think I will try the TRC foams after all. Maybe even for Sedan. Just starting to have too many problems lately with Jaco's.
RCRacer... I'd go with a Parma Speed8.
I also think I'm gonna go ahead and try the IRS axle as well. Found that my Yok axle end is bend. So my wheel wobbles a tad on the left side. It's not a bent wheels because I can put the wheel on the diff side and it'll be straight. No wobble. Uuuggghhh.. more money!!
Anyways, car was fast today. Just forgot to check tweak during qualifying. Racing 2 classes sucks. Next weekend I'll just race one class. Kevin you did good! We'll get them next time.
