Try a 30 shore frt tire,and or try a lighter spring up front,is your front sway bar parrallel to the ground ? more options to do but thats a start, also dont be shy in going over at the fast guys table and look at their car. Most fast guys around my track will offer good advice in helping someone out, because in my opinion its driving skill that puts them ahead.
Traction compond on rear tires 1/8 scale - NO
