You'll need a very forgiving front end on the hills!
Do not set it up like a circuit racer!

Give Luke at playskool a buzz! He's running a supercharged duratec now and will have good ideas on sprint rates etc!
Also arb's too

use Mallock's spring stiffness analogy. It was explained very fully in Staniforth's race and rally source book.
big travel from jacked at no load on your springs down to loaded height. Compared to nearly no travel for a fully aero car like F1 and LMP1.
3" to 4" (70mm to 100mm) from fully loaded to jacked up and no load would be a rough target for a no aero competition car.
Is it "static deflection"?

Welcome tymkea, but check the dates on old posts before replying as this tread is well over a year old.
