Hey GTSDean - I was hoping I could pick your brain on few suspension set up items. You seem to have a very good handle on setting up these cars.
1998 GTS with 70,000 miles. I've had it since 2012 and started going to track days (HPDE days, point to pass in designated zones) at the local road course last summer and have never had so much fun.
Bought the Miller 9660 kit (per your posts) this winter and used it to help install poly urethane control bushings. Also installed Eibachs (can't afford quality coilovers yet) and thin spring caps (1.5" total drop in rear, 1.0" total drop in front). Stock Koni shocks are adjusted to full stiff rebound. As you have posted setting rear caster is important for proper handling. And 9660 kit includes brackets for rear. As I don't have access to a DRBIII, and instructions for inclinometers included in 9660 kit implied they are just a digital level, I found a 2" square digital level that I was able to attach to the 9660 rear caster brackets.
