Kentetsu is on a distinguished road
Sure thing:

Rear swaybar I got used in a package deal. I believe it is by ISC Racing, and has three adjustment positions. I've always used the most extreme setting.

Respeed camber plates

Respeed coilovers (race version). Springs: Front 275/rear150 (note) everybody seems to think you need severe spring rates, but I argue that every time. The harder the spring, the less contact you will have with the road, and the less grip. Most of my serious competitors use front rates of 450 Lbs. and you can watch them "skipping" across the pavement on hard corners. In my opinion, you should only go has hard as you need to in order to keep the car balanced and level. The reason for that freeze frame was to emphasize this point. And besides, I can still drive my car on the streets, and I do so on a daily basis. While most of the others are stuck with trailer queens.

Respeed adjustable rear spring perches

Respeed front swaybar

Illumina front shocks

Bilstein rear shocks (no idea what they are exactly, they were part of the package deal of used parts I got).

Urethane bushings everywhere (yes, even in the rear upper links).

I can't put into words how happy I am with the handling the way it is now. I guess the best testament would be the fact that I've still got a Gforce Engineering trilink/panhard setup sitting on a shelf in my garage (another part of that package deal). I just never saw the need to install it, even though everyone swears by it. Maybe someday if I've got the extra time and nothing better to do (like drive my car) I'll install it and try it out.
