I've asked the same question a few pages back and no one seems to respond. I went out and ordered a ton of AE springs but they're not the ones I seem to need. I did however run the stock pistions with AE GRN (FRT) and AE WHT (RR) and it seemed to work fairly well. I still want to try the AE GRN (RR's) as that's what I believe everyone on clay maybe running.
