 | Spring Rates Anybody know what spring rates i should use in the front of my X1/9? Using 300lb in the front left and 250lb in the front right on a clockwise oval and suffering from bad understeer!

 | Re: Spring Rates The front of the car is currently too stiff in comparison with the rear so you either need to lower the front spring rates or push the rear spring rates up.

| | Re: Spring Rates Thanks for that.Think i'll lower stiffness in front. Had been using standard springs and the car wasn't bad, got a bit carried away with coilovers.

Easy to do but I'm guessing you've gone for standard 2.25" ID springs in which case it isn't too expensive to use the trial and error method. Just make sure the dampers are within the right range! Seen a few people make big mistakes that way.
