I'm reading into the 312mm brake upgrade, people all say you need bigger calipers aswel as the carriers, pads and discs.

Is the only difference between 288 calipers and 312 calipers the piston sizes? Asin 288 has 54mm and the 312m has 57mm pistons?

Rather confusing and no point buying and painting calipers when originals can be used?

Anyone confirm?

312 refers to the disc size but you need the 312 calipers and carriers for these. Piston size I'm not sure but posibbly bigger than the 288 ones.

Deffo one of the best things I've done to my car, it's nice to know I can stop very quickly if I need to!

I'm aware of people using the big carriers. Bigger discs and pads with original 288 calipers. To this day they are still using them with no problems. So it's all confusing to me!

AIUI:-

Golf MK4 288s and 312s run the same caliper. Our 288s run a different caliper that isn't carrier compatible with them. Hence, we need calipers, carriers and disks to run the conversion whereas the MK4 guys just bung on new carriers and disks.

If that's not most of the answwer then forget it, I know nartheenng...

Piston size is the same I think. I've seen them with 54 stamped on the side. Same size as they fit in the basic 256mm setups too.

Summed it up in one, cheers!
