how about this idea...staggered wheels, but BACKWARDS?

...Was always curious what Randy Pobst did on their race RS6's. Obviously worked.

BTW he's in my RS6 Facebook group, which is super cool.

Champion did everything they could (legally) do to get those RS6s to dance. Wider tires covered by huge fender flares, replacing suspension mounting points after every race, engine management mods, the works. The drivers said it was still a rocket-ride down the straights followed by a fight to maintain as much of the advantage as they could in the corners. Yes, it "worked", after a fashion.

I also recall the motors being tested after the RS6s had put up some eye-opening lap times at Road America. Suffice to say that the engine output was limited after the truth came out about just how much power they'd been making... LOL!

The RS6's run ended when Cadillac was allowed to basically field a prototype under a stock-looking body and blew the field away. Audi and some of the other competitors said "eff this" and went home. Ahhh, racing.... ;-)

Almost sounds like hands on experience, or running in the same circle?

If memory serves tires were limited to 275mm. Would assume the widest wheels possible with spacers helped fill the flares. Was a bit dubious on the purported 475hp - obviously restricted. Bet there was plenty torque to make up for it!

The RS6 is a fun GT street car but really shows it's weakness when pushed in slow speed 2nd gear corners on exit - even with a serious suspension and tire/wheel setup. A dedicated track tire might help hold the power, reduce push, likely in combination with addressing torque bias issues. Until I track the car can't speak for high speed balance- should be manageable- any dancing will likely require a bit of see-sawing on the steering wheel.

Friend of mine is a master body repair guy who keeps talking about making carbon bits for the RS6. Flares are #1 on the list. Told him he could slice up my car for R&D. Liking the idea of 305's at each corner.

Just need the demand....
