Koni NA - Big Thumbs Up!

maybe if you dont have a rear sway bar, but those rates are way high for an E30.

That's about right for a serious track car.

holy smokes, 1000lb/in sounds rather masochistic!

I had a leaky rear Koni SA shock with my Ground Control setup, so I called Koni NA to send both rears to be revalved for my spring rate.

Great experience! Repaired the leaky shock, revalved for 1000lb springs and repainted the bodies - they look brand new. All in a 2-week turn-around time. $234 for the whole deal.
