Since I had my shocks off I figured I would get the spring rates sorted out, My neighbor works for a Professional Porsche race team, And they happened to have a spring rate machine, Went today and checked out the shop, Right by Road Atlanta's Gate, very cool, Anyhow my rates on the rear are 110 over 230, and the fronts are 115... I am thinking they are a bit soft as I have a lot of preload, So I may mess with some spring rate changes in the near future...
