Which suspension to help hook better

Drag radials. If the car is going to be seeing the track a lot, i'd get BFGs. BFG's hook better on the track, but they wear faster than the Nitto's. The Nitto's don't hook as well at the track, but they outlast the BFGs and i've heard they are better in the rain, although not by much.

I have nitto's on mine and they really, really made a big difference. 1st gear was useable, no more getting sideways in 2nd and 3rd....

sub frames, lower control arms, drag radials should be enough

sub-frames full length (steeda) lower it upper and lower control arms. Check out steeda.com.
