Great footage and photos! Thanks for sharing.
Care to share your thoughts on the new 28mm front sway bar? I too am keeping things stock for C Street, and that's kind of the last big thing I can do other than 200TW tires. Body roll with SA Koni's on stock springs is still quite a lot...

Here's my latest AutoX footage from in-car:

This is from the last AX. Front bar on softest of two settings. Konis...front full stiff, rear 1/4 turn off full soft. The car rolls less for sure. Between the bar, shocks, and shoes Bridgestone Potenza RE-71RS 225/45R17....it's way less understeer. On Friday I get after it again. Going with the bar on stiff. I also want to remove the ballast from the rear bumper to reduce the swinging weight at the rear.

Love to see another Z3 doing AX! Keep me posted!

Please share your thoughts on the stiffer setting for the front sway bar. I have one on order and will get it installed next week.

Front roll was reduced quite a bit, but I have only tried soft. I am trying the hard setting, tomorrow. Overall, I love the way it feels. On full power, it pushes less. Ease off a bit, and it will go into predictable oversteer, enabling me to rotate using the throttle. I'm going out now to change the bar setting...stay tuned.

OK...full stiff is great. Noticable difference in front roll from the softer setting. I might even consider another mm or 2, if I can find a 30 mm bar with adjustments.
 
Got my track stickees on....worth 5 hp for sure!

L to R: Pueblo, LaJunta, Hallet, Second Creek.

So...did you find making it stiffer increased understeer? I would like to stiffen it further, but not if it increases understeer.
