I've searched the archives and found a couple of good threads, but they seem to die out. I'm possibly interested in lowering my RS6. I looked at the Sportec springs, but when I started to do more research, I found that 1) I'd have to disable the DRC, 2) ride quality would suffer, and 3) this would probably void the warranty. I was also looking at going up to the 20" Sportec wheels at the same time.
The question is, how many of you have lowered your RS6s? Is my research correct regarding the DRC, ride quality and warranty? What has been your experience? Good, bad or ugly?
