I'm in the process of upgrading the brakes on my wife's 89 535i with new front & rear 750i calipers and rotors. This will give the same braking as the 540i (E34)...the booster and brake m/cyl are no larger in the 8-cyl car. Not only are the rotors thicker but the piston diameters are larger in the 750i/540i calipers. The rotors are also vented in the rear. Appears to be a direct bolt on (you will need to buy the braker carriers as well). I'll follow-up with a racap of all of the parts, tools and fasteners needed to do the job once I've gone through the installation. SD (BTW...I'd avoid the cross drilled rotors. They do not offer any significant performance improvement, mainly cosmetic appeal. The ATE slotted rotors would probably be just as effective at removing gases as the more expensive drilled rotors.)
