Building a light weight street rod/auto cross car. Basic chassis/design of a 7. Widened, stretched to accommodate a trans-axle, IFS, IRS. Trying for a curb weight of under 1300#, distribution close to 50/50. Need advice on:
1) How to find target spring rates for the front and rear.
2) What resistance (lbs./inch) to use for stabilizer bars, front and rear.
A search of the archives was productive except that all the responses failed to note the inclination angle of the coil-overs. The suggestion of using between 0.5 to 1.0 X the corner's sprung weight could be useful. Chapman's comment that the prime mission of the suspension system is to keep the tire patch in contact with the road surface and that (before aerodynamic aids) this is best done with a compliant (as opposed to stiff) suspension, has always made a lot sense to me.
Advice, opinions, suggestions as well as references to online calculators
are all welcome.
