I recently purchased a 2007 RS4 and it has pristine stock 19" wheels that I want to keep that way.

I also want to spend some track time at High Plains and am wondering what type of track setup I should look at. Should I drop down to 18" rims and track tires or stay at the 19" size with track tires?

Any advice/suggestions and or actual experience would be greatly appreciated.

Thanks,

Michael
