I am about to buy the double adjustment coilovers, this is on a turbo full race car, with wheelie bars, and they told me to go really stiff up front and really soft in the back, like 85-90 pound springs??
this is the first I have ever heard about that, does anyone have any input
thank you

 

yes, for a wheelie bar car you want soft springs in the back so you can utilize the wheelie bars as much as possible

we run the them on a non-wheelie bar car with about 450 ft lbs up front and 800 ft lbs in the rear for the springs

 

i own a set of those strange suspension and i think they are bad ***... i have mine set up for a street car though with stiff in the front and not so stiff in the rear. i noticed a lot of traction improvement not only on the track but on the street too.
