Hello, I've got a 2006 Z51 MN6 as well, and I autocross. I've put in a purchase to Randy for a set of DRM Bils that should arrive in a couple of days. After I get those in and run a few SoloII's to see where the balance is, I'll be looking at a front sway bar (probably one of Sam Strano's). From what I've read on this forum, sounds like we're basically taking parrallel paths in development here. I run Toyo R888's currently, with -2.3 camber up front and -1.2 in back and did have to lower the car a bit on the stock bolts (max in the back and not quite that much in the front) to acheive the alignment goals. I'm curious to hear how the Bils worked out for you, how it affected your under/oversteer, whether you've already put a front sway bar on, and if so what size etc...
Best,
Sidd
