Anybody know what the hat offset of the 86 Turbo rear rotors is? Brembo has the 87-up posted at 100mm. I've been looking everywhere, but NADA. I have an 85.5 NA with a 5.3l V8 engine and doing brake upgrades for obvious reasons.

 

Welcome. Post pics!!!


....and I have no idea the answer to your question.

 

I designed a dual MC housing for the swap and also designed brackets to install Lexus LS430 4-pot calipers and Boxster S 318mm rotors for the front. I am going to start the swap for the rears using 4-pot RX7 calipers next (they're sweet). RX7-944 control arms have been finished. Bump steer kit has been designed already too.I also put together a basic swap kit to put any chevy v8 in the 944 using a vette C5 bellhousing. A V8 swap manual is now available from another guy on the hybrids site and headers are the only thing being worked on by a few people there. I used Hooker 2312 headers and modded them to clear the steering shaft...works like a charm.


Massive Lexus 4-pots and Boxster S rotors....




LATE and EARLY offset selectable RX7-944 control arms...

 

How are these doing ?
