im using 285mm cross-slotted ventilated VL turbo discs and twin piston VL turbo callipers
with half decent rear end this will stop a ten second drag car easily

I run ca18det front struts, brakes etc and r31 skyline castor bars. Bolt in stuff apart from putting the correct thread on your 1200 tie rods to match the ca outer tie rod ends and using 2 driver side inner tie rod ends.

What type of booster and master are you guys using?

I'm currently looking into the Ford Falcon brake upgrade (and change to Ford stud pattern 5/114.3)) that was mentioned here a while ago. I'll post more details when I've looked into it further, but I can tell you for sure that the XB-XD models that were mentioned before is incorrect. It's the XW/XY that share the same wheel bearings as the 200B. 287mm vented disc and single piston slider that fits inside a 14" wheel.

BTW, Feral is dead right about the increase in wheel tyre diametre affecting braking performance. The percentage increase in rolling circumference is exactly the amount of braking ability lost. It's pretty common knowledge amongst guys modifying 4WDs who like to fit monster tyres for increased approach/departure/ramp-over angles.
