Z3 rear calipers

[Fraser]

Hi all, does anyone know if the rear calipers on the Z3 are the same as the E30 or E36 3 series?
Thanks,

As far as im aware they are specific to the Z3. Realoem seems to back this up.

You can fit Z4 callipers, but, you have to bleed them with the calliper dismounted from the carrier because the bleed screw is at the bottom. They are much less expensive than Z3 ones and work perfectly. I recall @Sean d did this and found out about the bleed screw.

and found out about the bleed screw.

My, that takes me back. A mistake he'll never make again.

Z4 caliper work very well, they have a bigger piston as well which adds more breaking power, they balance very well with 330 front calipers and discs, as Tony mentioned it took me weeks to realise you have to bleed them the other way up

Cheers Sean, I thought I had remembered right.

Tony.

ps. Just thinking about it you could fit them the other way up but it would mean rerouting the hose.

Thats a good tip to keep in mind (using Z4 ones)

I have a pair of Z3 ones, I was going to refurb them but never got around to it

Do you also need to use the Z4 caliper mounting bracket with the Z4 Calipers on the Z3?

I dont think they fit, I think I ended up fitting the z4 calipers to the z3 brackets but I.m not 100% sure
