Driving (6th HPDE) the Road America on 9/6-7 with my 06 C6 A6 and R6 slicks on OEM wheels.

What Camber (F & R) with Hardbar camber kit should I use? Any Toe?

Thanks.

You should always use a little bit of toe F and R to keep the car stable and to help on turns.

RA is all about speed, so I'd recommend just a little bit of toe out up front and the same amount in back. ...maybe about 1/8th total toe.

RA is primarily a turn right track so I'd say about -3 on the LF; -2.5 on RF; and about half those numbers on the back (depending on how good your bushings are).

Uh, take lots and lots of brakes!!!!!!

I aggree with Chris on setup. Road America will eat up your brakes. I carry Cobalt Friction pads, in stock for your car. Unbelievable stopping power and will outlast any other race pad out there. Call me if you are interested, 630-844-0089.

Thanks. I am using DBA 4000 rotors with XP10 F & XP8 R (extra set ordered). It is difficult to get much more than -1.25 on the rear of a C6 even with Gary's kit. Rear bushing are stock. Should I replace them with new ones? A different brand?

You may have to slide the crandle over to get the right amount of camber on the one side.

I set-up a few cars for RA (since it's 15 miles away) and one thing that I do different than any other track is set the rear toe to 0, the only reason is because between the kink and turn 12 the track is a little curvy and your blasting through there at 110 - 140 mph and if you toe in the rear the car will be a little "darty" through there, it kind of depends on the driver some people don't mind it others want the car to feel planted underneath them.
Just a little tip.
Otherwise do everything everyone above said, epecially about the brakes.

Make sure you check the fluid in your clutch reservoir too, swap it out if its dirty. RA can be hard on clutches as well.

It just depends on how much you track the car...and how fast you want to go. Polyurethane bushing (thru Vette Brakes and Products or wherever) is a better solution than stock, but you'll increase ride harshness on the street (if you care about that). With those bushings, you can run less negative camber, so the tire is straighter up.

I would look at upgrading your brakes to the XP12s Front and 10s Rear for Road America. You'll need it.

A little curvy with walls on both sides.
