I came across these AP Racing kits by Essex. Not sure if anyone has pointed these out already, but I've always been a fan of AP Racing brakes so thought I'd pass it along. Both of the Mustang kits in the link below come with 6 piston calipers, 374mm (just under 15") rotors and use the thick endurance pads (like the Brembo race / 302R calipers). With two kits costing $4100 & $4500, they appear to be a bargain compared to the equivalent Brembo kits.
