Had a thought the other day and would like to know what some of our autoX guys might think. I'm contemplating a set of wheels and R-compound rubber for autoX. I'm thinking that by going to a 15" wheel I can (1) lower the car about 1/2" and (2) get an effectively lower gear ratio. The side benefit is that 15" wheels and rubber are marginally cheaper. Will 15" wheels fit (the spare tire is on a 15" wheel FWIW)? And are there any negative effects that can be foreseen? Thanks
