    What is the advantage to going to higher spring rates?

    Less body roll? Was that a trick question?

    Seriously, at some point, there is too much spring for this car. I am just not convinced I have found it yet. I have ceratinly sacrificed wet-weather performance (I can run just as fast in our SM rental cars in the wet) for dry weather grip.

    The issue with this car is that it feels great no matter what you do. With our ITS RX-7's, you know immediatly if you did the wrong thing in terms of set-up. Finding the fast set-up for me is done primarily with the Data and the stopwatch.

    John, Let me recommend speaking with Shaikh at Fatcat Motorsports in CA. He has done a lot with the Bilstiens. He is a very good source for info on what you are looking at.

    Lower static ride height to gain camber while staying off the bump stops?

    That's why autocrossers use the higher spring rates. I'm thinking as fat as that SM swaybar is there's plenty of roll control. I'm a total noob when it comes to this Road racing stuff and I never imagined there was so much to think about, worry about, set up, configure, tune, tweak etc etc. Maybe I'm overthinking it. I take advice well and learn from trying so this should be fun getting the license. I'll worry about getting faster as my seat time goes up. Thanks for the info.
