I have to say that shocks will have a very big effect on how well the SS springs work--You have a race car right? So buy some real race shocks
It is impossible to beat the KONI SPA-1's on the front If you set them where they pull apart the easiest you are ready--If you can't source them use QA-1
On the rear the QA-1 adjustables are killer--call them for part numbers about three clicks is great starting point 4 clicks on killer tracks
You just need to look at pro cars and see what is on there--I know most are going Caltracs these days but even so ask the pros what shocks they are using
Makes ALL the diff in the world to go ahead and drop the loot on real race shocks
