according to a conversation i had with vorshlag (running top 3 in both scca and nasa in their REGION in both autocross and road courses)...
biggest difference you can make to the s197 is by moving to 18x10's square
behind that, lower control arm BRACKETS make the most significant difference above all other suspension mods on these cars.
nobody in the world knows more about putting the power down than vorslag
springs and shocks and plates. they of course, recommend their monotube setup which has all 3. bilstein dampers.
