What would be a good set up for tracking and autocross clearing rotora calipers....im looking to get the work emotions but not sure if any one has tried their 17x7 and 17x8 set up on track...please tell me if it runs well...i was thinking maybe of 17x8 and 17x9 but not sure if proper offsets are available with a 1.5 in drop and clearing the BBK.
