UrQ 16 in. wheel possibilities?

[RndLiteBMW@aol.com]

I have a few quick questions about putting 16" wheels/tires on an '83 UrQ. 
I'm looking to lower the car with H&Rs, and need to know the following: 
	
	-How wide can I go with the wheels and tires with unrolled stock 
fenders?

	-How wide can I go after rolling the fenders, ala 84-on UrQs?

	-What is the proper offset to run in order to prevent rubbing?

	-What is the lug spacing, and is this pattern the same as later 5 lug 
Audis?	(wouldn't a set of A4 sport package wheels look great?)


										
				Thanks for the help,
