After reviewing all the options, i decided to go with the Rebel Racing 996 brake package.
Its bolt on and i have bought parts fron clint@rebel before.
All the RSR suspension parts i have had previously have been very good quality, i know it will work, and they look so good its a shame too fit them where they are out if sight! (however makes me smile later when i am under the car servicing it...)
Larger diameter and thickness rotors are offset by lighter alloy hats, which supports my aim to keep the unsprung weight down. I did not need to go overboard with big heavy brakes as car is on target for being well under 2200lbs.
996 on the rear too.
Have removed all the e-brake weight and mechanicals as will be running the Voodoo13 hydraulic handbrake.
