Mixture
Bill,
Sorry - I didn't know which button to hit, as I am running AP CP5040s on the front with 315/28 discs and Wilwood Powerlite's on the rear using the standard Granda Cosworth disc. I can't tell you how it performs, but I can tell you the reason why I went that route.
APs - I could not resist a great offer from another forum member (a big thank you goes to that excellent fellow Dave Morton), which effectvely allowed me to put a great setup on the front, for about 2/3rds of maybe buying it from a supplier.
Wilwoods - Here in the UK a company has worked with Wilwood to develop and integrated handbrake into the caliper. This currently is only available on the smallest caliper in the range and only fits a 280 disc. The pad area is a little small but should hopefully get me through the government test if I ever get the car built... They hopefully will also develop the next caliper up (billed as the Dynapro on the wilwood site), which takes up to a 310 disc and has a larger pad area, so I willupgrade at a later stage (maybe). I also, managed to do a deal, so all in I should be able to put the rear brakes on the car for just under £300/$750 (AUS).
