please help and thanks!!!
The stock struts and shocks simply can't handle the extra spring rate.

Koni just came out with the xi struts. Rear shocks are the same. You may want to consider those if you are concerned about ride quality. Lead time on those are about 4 weeks since they must come from Holland.

Right around xmas time there will also be a Koni SA coilover system for the xi if we can find a local xi for the R&D.
