For those of you with RS4 rims...
 

Any noticable decrease in handling balance/acceleration from the additional weight? I'm thinking of just getting 17" RS4 reps rather than waiting around for a good deal on OE wheels.

my car handled better, due to the sidewall decrease and width increase..
 

they are not any heaver than the stock wheels as far as I can tell.. when I mounted them, I didn't groan like I did with Liam's OZ Sls.

Nope. Better handling. Unless you're hardcore about
 

weight and track your car, it's not significant when it comes to acceleration.
