Ran 2 days of autox this weekend with my new mods, and want to report I am very happy with these:

Racing Beat front swaybar & endlinks
Kuhmo Ecsta MX 245/40/18
-1.5 deg. camber, front, -1.0 rear

This combination really made a difference in turn-in! In my April experience, the car kept pushing thru turns, so I compensated for that by turning in early.

On my first run on Saturday with the new setup, I drove the same way, and ran over cones right away. The car now gets to the turn-in point almost as early as I turn the wheel.

My mechanic put the car up on a rack on Friday to tighten up the endlinks, and I finally realized why people are saying the exhaust should be replaced. That muffler is gigantic!

Editing my 'duh!' comments.
Everyone says straight thru is way too loud.
Looks like RB is out now.
Is there such a thing as muffler 'weight to performance' ratio?

 

Thanks for the feedback - it's nice to see more people validating the front swaybar approach. I like your tire choice as well - a very good setup for running street tire, I'd say.

As for light exhausts, it seems like they all do the same power wise (which is to say not much) so just look for a light setup. Canzoomer sells a titanium setup that is probably quite light, but it must be pricey.
