@ dan - 735i calipers

Did you run the E36 M3 calipers with E30 M3 suspension? How did you make them fit?

I'm running a 25mm MC with the Clio servo and E30 M3 calipers. I think the pedal is a little heavy but that's probably just me. I'm a small guy. Hoping to upgrade to larger calipers in near future.

you might know more than me!

the 540 and 735i calipers are identical. (watch out for some 730i models which feature thinner disks)

I have run them with 23mm MC and 25mm MC

Both work fine but the smaller servo I would try a 23mm first.

compared to the 23mm MC the 25mm MC just feels firmer and a has less travel. It didn't feel to me that much more effort was required pushing the pedal to brake hard.

All depends on the brake pad choice. I used a set of PAGID Yellow RS29 and found them too agressive for my braking style. I could lock the wheels up with moderate pedal force

Pagid Blue RS4 was very good and after these I used AXXIS Ultra which are very cheap compared to real race pads but won't last as long.
