Default 87-up Turbo Rear rotors on 85.5 ?????

I looked everywhere and cannot find if anyone has put the deeper offset (100mm) Later Turbo Rear Rotors on the Early offset cars and the parking brake still function. I figured the adapter brackets needed to put the 4x36 RX7 calipers on the rear of the 85.5 NA rotors, but it is a complicated drawing. If the Later Turbo rotors will fit and the hand brake still work, the brackets will be an inch thicker and simple to make....

Default Rain Check

It's raining here, so hold off on that dimension and I will post it up for all the world to see when I get it mic'd. It will obviously be different with the larger diameter 86 Turbo rotor mounted.

Default RX7 Brakes are Done

I have the Adapter bracket prototypes finalized and will be ordering T-6061 Billet material to CNC the brackets needed to put the FRONT 3rd Gen (92-95) RX7 calipers on the rear of our 944's with Turbo Rear Rotors.......
I'll be shipping a pair for $145 anywhere in the 48 U.S. I need a head count, so Hit me up.

Has anyone used the LS430 fronts and decent rears in conjunction with the manual tilton dual set up yet in practice? I know Tim is working on it, I am just wondering if I should consider this my answer, or keep looking at assisted options.

Default Phoneys

Hey 3rdgen, are you running 15's or 16's?
Last night I test fit the RX7 caliper on the 318mm Diameter Boxster S rotor and front NA spindle with a 16" Fuch and it clears nicely. The 15" phoney is a no go, but with stock 282mm Diameter Rotor installed, The Rx7 caliper works under the 15 phoney.
