I'm looking for recommendations for the best size wheels and tires for autocross, including wheel offsets. Rubbing has been a problem for my 205/50/R15 with 15x7 +38 mm wheels, and I need to upgrade to stickier tires anyway, so I'm wondering if it's worth the money to get 41 mm offset wheels, or maybe just go with 195/50/R15. Any advice for a high-performance setup is much appreciated.
