I have SPF #2743 with the Willwood combination E-Brake on the rear with 34mm pistons. I'm running the Roush 427SR and Superformance recommended a vacuum pump which the dealer installed. It's an Electric Vacuum Pump Kit 28146 manufactured by Stainless Steel Brakes Corporation (SSBC). The new calipers with 41mm pistons provided by Superformance will be installed within a few weeks.

I haven't tried any aggressive braking as of yet but under normal driving everything seems fine. The fronts do lock up before the rears.
