    E30 racers; what type of handling >>>>

    issues or characteristics should I expect with heavier front springs than rears? For example; 1000 lb fronts and 800 lb rears? Oversteer, understeer? Thanks!<img src="http://www.provento.blogger.com.br/karate-kid.jpg">

    Is the rear a coilover or standard inboard spring? Those are very high spring rates...

    If it's an inboard spring (factory setup) you can get away with running a significantly higher spring rate as there's much more leverage further towards the inside of the trailing arm radius. How heavy is your car? Those are pretty high rates all around...Better be running some sticky sticky sticky tires ;-)

    I'm running a 350lb spring (outboard....coilover) and she seems quite stiff enough (and I have an 18gallon fuel cell in my trunk). My fronts are 550 lbs but with more testing I'm sure i'll change the springs. Note, I do not run swaybars. My car weighs 2400 lbs wet with me inside. I suppose I could go a bit stiffer...only testing will tell.
