hey guys and girls

I am currently running Koni yellow shocks with Eibach springs on my mk3 VR. Front and rear.

Currently the front are fine and the stiffness of the springs suit me well. the rear though are a little too soft.

I am purchasing some spacers for the rear for a little more poke (nothing drastic) and I wanna keep the koni's.

can anyone point me in the right direction for low, heaps stiff, rear springs? I dont wanna change my whole setup, just the rear springs

thanks
eric
