iX master cylinder piston size

[Roysneon]

Does anyone know what the size of the iX's stock brake master is? Anyone know of a larger one that will give a stiffer pedal that will bolt up to the iX booster?

I know that M3 and 750 e32 are upgrades for non-iX cars but they won't fit on our boosters. I think that e36 masters will fit out boosters but once again I have yet to verify the piston size on the e36 ones.

It says 20mm... :)

Its the same size as a regular e30

Im pretty sure the 750 e32 is the 25mm vversion.. i had one, ill have to look

But does the 750 one fit the iX booster stud pattern?

[nando]

Yes.. it's the E32 booster that's basically the same as the ix.

Awesome. I have a brake booster from an e32 735, I just didn't think to look at the master cylinder when I pulled it. My car isn't an iX, just 24v swapped. I'm doing an e30 M3 5 lug swap and want to go with a master cylinder closer to the e30M part that will fit the e32/iX booster.

I'm interested if you can do anything with the E36 one?

[Roysneon]

Apparently so. I'm gonna have a look at a car someone I know is parting out later this week to compare.

I'm going to pick up a used e34 master cylinder and fluid reservoir to test fitment soon. Will report back with my findings.
