Well Autocross is coming soon and I just started to test the diesel for auto cross. I know the springs and shocks are just not where they need to be so I am seriously thinking of doing some upgrades. I have narrowed my search to two brands.

The Koni sport (8741-1092SPORT) and the Bilstein sport (24-014700).

Does anyone know anything about the differences of these two? I know its a slow diesel but the tighter suspension will help.

thanks in advance.
