What spring rates do you recommend for an A4 Quattro 2.0T for daily driver that sees occasional track use?
A STaSIS Track Sport suspension that runs a 600lbs front and 1000lbs rear will suit your performance needs. Note that the rear spring rate is measured somewhat differently due to the design of the suspension on these cars. This is a common and comfortable yet firm spring rate to match the 600lbs front springs. We have several A4q2.0 running this setup with great results.
