That's a pretty useless link given the question...

Tourings used a slightly larger piston on the fears. Not sure if you would really notice it. WMS do a nice looking rear calliper upgrade.

What have you done to the fronts to make you think you need to upgrade the rears?

BMW Z1 rear discs with E30 M3 rear calipers is a bolt on upgrade. That gives a 282x10mm rear disc, but at 10mm thick it's still a solid disc.

The other option is compact or Z3 rear callipers with a disc of your choice (probably a redrilled compact/z3 one for 4 stud people) and they can give 170mm ish or bigger for Z3M bits.

Again still a solid disc, Is vented really needed at the rear? Even e30/compact race cars don't comment on rear disc fade.

We have stock e36 compact discs at the rear of the s50 powered compact and never had an issue.

It's just I have my hydro plumbed in and it doesn't even lock the Rears unless I really pull hard on the wand!

BUT....if that's not working with std bias, any fix at the rear axle will mean adding rear bias and making the car overbraked at the rear.

Put a larger master cyl in the hyraulic handbrake or change the leverage?

That would be my suggestion.
A lot of people pick a cylinder based on foot brakes and your arms give nothing like the force of your legs.
