Wilwood bits ands pieces that will be available.
From Brian Hasty:
"I will be using the Superlite series of calipers. The Superlite IIA cast caliper will be the base caliper, with the Billet Superlite available as well as the Billet Superlite 6 piston. Rotors will probably be the 12.2" directional vane design. Options such as HD rotors and drilled or slotted rotors will be avialable."

If da budget can swing it I'll probably go with the Billet Superlight IVs and some minimal cross-drilling. Figure 8 lbs reduction in unsprung weight based on the fact that stock calipers weigh approx 12 lbs each, the Wilwood calipers 6 lbs and stock rotors weigh 13 lbs, the 2 piece 12.2" rotors 11 lbs
