hi guys i know its a long shot but a few people have used r31 diff's
so i need some caliper brakes that have an combined mechanical park brake and was wondering if anyone knew what was the smallest size rotor they are compatible with.
as long as they can work with 11" rotors i should be right with wheel size, they're sat pretty far inward so they're on the largest part of the wheel
otherwise i guess im looking at seperate handbrake if anyone knows whats best, wilwood ones seem decent
cheers!

for this

Showing a bit of leg there

Can
You use front break calipers off a Suzuki swift or something else that uses 12 or 13 inch wheels as they will have similar sized disks

haha sneaky bit of skin in the picture
finding small calipers should be easy enough, it's more finding something with an integrated mechanical handbrake
if i go separate handbrake caliper it'll be easy enough though

not sure if this the answer to your question but

r31 diff brakes can run 13s. had 13s on the back before.
they are one of the smallest disk brake calipers ive seen lol

Depends on off set and cast of rim I would gave to grind càliper to fit neatly.

Integrated handbrake an issue

standard r31 disc is only 260mm or there abouts. subaru L series also have a mechanical/hydraulic front handbrake caliper. but think its a bit bigger than r31.
s13s and pulsars also use mechanical/hydraulic rear calipers

so are you running inboard discs and outboard ones for the handbrake?

thanks everyone, pigdog had the exact answer im looking for

well with integrated handbrake i only need to run one caliper and it will be outboard i guessbut the rotor is just backspaced anout 15cm from the hub face, so instead of sitting where the step down is in the rim its sitting in the edge of the rim where it is largest internally

oh and if anyone has an r31 calipers i guess now im in the market
