Brake upgrade questions

[cody at 5000tq.com]

Ok so I'm preparing to install a BIRA system 3 on an urS4. I was  
wondering about fitment of the urS's old schtuff onto a 5ktq.  
Possible? Easy? Worth it?

I'm not in a position to spend the kind of money needed to do a proper  
brake upgrade, but since the old urS4 caliper brackets, calipers,  
rotors, et al would be either free or close to it my little lightbulb  
lit up. I'm sure I'd need 16" wheels... I could work on that, maybe  
beg/borrow/steal a set I know of laying arround ;-).
