Why 18" vs 19" wheels/tire for track and Auto-X

I never found reasonable 18" wheels that would be legal for CS, but if I had, this would've been the main reason for me.

At current prices, RS3s are $400 a set cheaper in 18" sizes. From the looks of things, I'm going to burn through 2.5 sets in one year of autocross in my car.

Granted, that's doing every regional event including practices (in SoCal, so one a month year round), 2 ProSolos, 2 National Tours, and Nationals next week, often with co-drivers.

I'm getting around 120-150 runs out of my RS3s, flipping them and rotating them.
