Ke30 disc brake rear

[RACINROLLA]

Hey guys,
So my race car is coming along slowly......
I want to convert the rear to disc brake from drum...its a KE30 rolla with a T50 box and 4age motor...(not in yet)
What have you guys done or heard of using too
1) convert to disc rear end
2) use a stronger diff
3) go to a coil sprung rear end....(not allowed to change mount points for IPRA)(so probably out of the question)

Any advice would be awesome!
Thanks guys
Cheers matt

run a single aluminium leaf with a coil-over and anti-tramp rods to get around those rules.

As for the disk brake upgrade there's a guide valid for almost all toyota diffs in the articles section
