Anyone know the uncompressed length of Centerline's rear performance springs for a Spider? I just completed installing their springs on the front and rear and the rear end sits bottomed out on the rubber axle bumpers. The front actually sits 1" higher measured at the wheel arch than it did with the old springs. I guess my old front springs have seen better days. The uncompressed length of the rears that they sent me are 11 3/4" long. They looked really short compared to the originals, much more so than the shortness of the front springs compared to the originals.
