How's the ST overall as far as maintaining alignment and eating tires? I'm curious about running staggered sizes, but obviously alignment needs to hold up good since you can't rotate. I haven't seen much of this while searching like with Mustangs and such.
If you drive hard, you are going to need to rotate the tires. The front end requires a lot of grip. Maybe the best option is to run an asymmetric tire like the Re760 Sports? It should hold alignment just fine but just like a regular platform, you will probably get more wear out of the wheels that get power.
