Anyone know the spring rates on a 993 cup car coilover package? The numbers on the springs are:

The front springs are ERS 140-60-140 and the rears ERS 140-60-160. All four "Tender" springs are ERS 50-60-40/120.

Is a cup car suspension even worth doing on a 993 D class PCA race car (track only) given the obvious weight difference between a cup and stock car? Any input is appreciated. TIA

John, talk to Greg F. Everyone I know running the 993 is way up there on spring weight 700-800 F 900-1100 rear (these are D and C cars)
