Hi, does anyone have any experience with the 750i master cylinder, I have one from a donor car but it made the brakes feel quite hard

Has anyone found them to be beneficial ?

Thanks

No point unless your fitting calipers with larger pistons to match Jim

I have one with the WMS kit on the front - not as big of a difference as I thought initially, really just a bit firmer with less travel (slightly less spongy, but it's still kinda like putting your put in a bucket of jelly.

Cheers,

Thanks guys

I have WMS front calipers and standard rears, so do you think I need or will get any benefit from the 750 MC?

Quaser, if I dont need it, its yours mate.

No benefit at all, its actually a downgrade

The WMS calipers are a close match to the E30 pistons so you dont need to change the master

I've heard of people needing to use the 750i 25mm m/c with some Wilwood calipers, but as Dan says, the WMS ones have been designed to work properly with the E30 m/c.

I ran a 25mm m/c with standard 325i brakes for a short while and it really wasn't great for day to day driving.
