Audi supplied all RS6 C6s with its Dynamic Ride Control that offered three settings: Comfort, Dynamic and Sport. Most owners report Sport is too firm for use on the road. An uprated front anti-roll bar helps quell understeer in the RS6, but don't expect much feel from the hydraulically assisted rack and pinion steering.
Tyres, discs, pads - it all adds up!
Some cars are now beginning to suffer from failing rubber hoses in the suspension system. This is usually caused by the connectors between hoses corroding. The dampers can also leak, though this is not a common problem.
More of an issue is the rate the RS6 gets through brake discs and pads due to the 2,025kg weight of the car. A front set of discs will cost £1,175 from Audi, while rear discs are £945. The pads are not as pricey, but reckon on spending £400 at the front and more than £200 at the rear. A more cost-effective option is a full set of Ferodo DS2500 pads for £270. You can also opt for an AP Racing brake disc set-up that costs much the same as the standard kit from Audi but offers better stopping power. This does involve swapping the bells the discs sit on too, and that costs extra. Replacing the optional carbon ceramic discs will set you back £2,000 per disc though they do offering superior stopping power for those interested in track days. One other brake upgrade you could look at is fitting the ducts from a Volkswagen Phaeton, which are a direct fit and offer improved cooling.
Given the RS6's weight, it's no surprise it likes to get through tyres. You can spend as much as £1,600 if you order them through an Audi dealer, but more realistic is £235 per tyre for Michelins in the original 275/35 ZR20 size used on both axles.
PHer's view:
"Always wanted one, was in the right position to do it, so thought I might as well get it out my system while I can."
