Where do you race OP, Holly Springs? That track is in MS right? Or do you guys go out of state?
If you do a Whipple and a converter slicks will get the job done, drag radials might it depends on how good your local track is.
You don't need any suspension to run mid to high 10's/ low 11's, but personally I'd like to get a set of adjustable shocks for the front some day.
I did toe rods and trailing arms and I think my car hooks worse now.
