I was wondering cuz i have Rs4 wheels/tires sitting at my storage right now, i could use them instead of buying a new set for my daily, are they to big/heavy/wide for my daily! Thanks
I’ve seen them on several b6 S4s. So I’d say yes.
Depends what you mean by fit. To get to the wheel shop in an emergency, yes.
To daily drive, no. They will look retarded, will poke out a funk ton, and will generally be embarrassing.
Haha thats what i was thinking! 
If you don’t want your OEM wheels, maybe sell them. They’re pretty valuable on the market if you’re patient. Guys are getting upwards of $1500-2000 for a set.
Nha i will keep them for a while in case i decide to sell the car
