ok ok forget try this try this, can you use stock calipers and uprated pads and have just as good stopping power, or are the 750 caliper a 4 piston setup
and the rotors bigger, i did replace my wheels for 15inch 750 wheels, please only facts don't tell me you think this will fit or this will fit thanks kelly...

I don't understand what you're asking. You say "can you use stock calipers and uprated pads and have just as good stopping power". As good as what? I think filling in the punctuation might help.

750's calipers were 4 piston only in Europe.

i wanted to know if for street use if just upgraded pads would give you all the brakes you needed, or is the bigger brakes just over kill on a street car

It won't be overkill the 1st time it saves you from a SUV driving soccer Mom (or Dad) who swerves into your lane while screaming at kids. After changing all the fluids, it is my first order of business on a newly aquired e28 or e24. Also the e34 rear brakes are a major improvement

:) - true...

I can vouch for the E34 rears. Steve put them on my car and the braking is much "flatter" and controlled.
