[s-cars] going BIG

[derocco_16v at comcast.net]

So, I have been planning on upgrading the "fabulous" stock brakes on my S6, to some more "meaty" ones out of a boxter. I need to decide what rotors to get, and I would like to go with whichever product is lighter [ I guess] Is there going to be a significant difference in weight between OEM A8 rotors (312mmx25mm) and aftermarket crossdrilled/slotted Zimmmerman or similar, or shold I not pay attantion to weight factor and get the less expensive ones? 
Thanks!
