Hahaha, that's gonna have to wait until engine swap. The only E21 coilovers worth my time are GAZ out of England and I'm not gonna spend the money to have them shipped here when I plan on ditching the E21 suspension geometry altogether at some point in the future.
I will probably end up having TC Kline make me a custom setup as I will have E36 running gear up front and E28 in the back
