I back the Caltracs right off for the street. If I leave them preloaded it stops the suspension working as it should, if I just back them off a little they bang against the springs all the time. I have QA1 single adjustable shocks all round and Calvert mono leafs. I should point out that I drive the car a lot on the street.
