Lowering Springs for Superformance (TIRES ?)

[agro1]

Looking at lowering my Superformance for track use only. Any suggestions ? How low is too low and what are the best springs to get ? Will I need to get different shocks if I change the springs ?
I want to keep the 15" rims but would like to put slicks on'em. Any suggestions as far as the size of the slicks ?
Thanks in advance to all who reply.

in the 15 inch sizes, many folks, including us, run DOT Hoosier's, they make a radial and a bias ply specifically for these cars and the 15 inch rims. Very sticky for track use, I think they are about $180 or so a tire. I have mine on a spare set of Trigo's.

The springs on the car are on threaded shocks, so some adjustment is available right on the car. New SPF's now come with custom calibrated and valved Bilstein shocks. Many of us run our cars on various road and drag courses, and lots of information and experience is available. Many of us have also modifiied our cars, Halon systems, fuel cells, engine, and so forth.

Get the Billstein shocks, the AVO's are oil filled and get spongy on the track as they heat up. Different springs in whatever length and rate you might want are available from Eibach.

I have the Billstein's and have been looking at the Eibach Road Race Kit - would that work for the Superformance ? Just wondering which one to get ?? Thanks for the reply !!
