I'm building a Diablo Roadster using a replica frame. I have 400 pound springs on the front and dual 250 pound springs on the rear. The bushings on the rear shocks seem to be fine but the fronts appear to be distorting some after just sitting in the garage for the last year. And the only weight is from the frame itself and the body (body not permanently mounted so is off and on). Anyone had an issue with wearing out shock bushings quickly on this type of setup?
