Thanks for the responses. Agree the stock front rotors are heavy (20 freaking lbs each!) which is a good thing for track use, but for a nose heavy auto-x car I'm hoping to find some weight savings. The two-piece "hat" style is the approach, with an aluminum center "hat" and an iron ring. Problem is while it looks like they'd be reasonable at Coleman Racing, nobody has a ready recipe for which hat and ring. Maybe I'd do best to send them a stocker and see if they can match it. So thinking about that, a crap-tastic one near MI would be a great thing...

As for gears, the stock ZR-1 gear is 3.45. There was a 3.54 used somewhere in a C4, which makes it an okay swap in my rules setup (update/backdate among all c4's). It's not much of a change but any advantage is an advantage nonetheless, and the 'big guys' are all using them. It'd be more effective with the cammer though!

Last night I suddenly realized that my Bronco has a 3.54 D44 in front.... Hmmmm...... There's only 170k on that set!!

Best,
- Jeff
