Thanks for the reply, these may fit the bill for finishing my ST3 car. One question; when you swapped the rear spring for a 300lb one, did you have a wing on the car?The H&R RSS Club sport are a very good entry point coil over. The rears springs are to stiff and can be swapped out with a lighter coil over type spring depending on sway bar choices. SMGDHG has them on his car now. He runs great times with a 08 4.6.
