I want to go to something stiffer, since those are pretty soft rates, and definitely switch the rears to linear.

Relevant info for the car: Daily driven with around 10-15 track days and as many autox events as I can possibly run in a season.

Current modifications (apart from the SACHS coilovers): No real power mods (only thing apart from suspension is a muffler delete and drop-in filter), 17x8 wheels with 225/45 ZII Star Specs, and original Whiteline LCAs. I'm trying to sort out my camber plate situation, but once it's finally figured out I plan to run F-2.5 and R-2 to start with.

Seems like, based on what I've seen RCE and CSG suggest/run, the cars tend to do quite well with 400-450 lbs/in squared or F 400 lbs/in R 450 lbs/in.

Given the info above I'm leaning toward Hyperco 450lbs/in springs all around, but would certainly appreciate any information/input from those with greater knowledge and experience on these matters than myself. haha

Will you be able to have the damper revalved?
