I can check e92 ZCP spring part numbers tomorrow for you guys. I have my stock pair in storage.
Montaver FWIW, I absolutely LOVE my ZCP + H&R Sport Plus (stiffer than regular Sport, but same drop) + the shaved top mounts/E36 M3 bumpstops combo. I wish it was like this from factory. It never bottoms out, is super smooth and composed and just the added touch of stiffness to make the E9X feel more aggressive and tilt the sport:luxury ratio nicely to the left
