Depending on what kind of racing you're doing, offset wheels may be useful or not. Remember that most 24mm racing wheels probably won't be available in various offsets. 0-2 degrees is most likely. 26mm wheels can be found in various offsets but keep in mind that most racing classes specify 24mm tire use. Hope that helps. The TT01 is a GREAT spec racing chassis.
Actually, the TT01 shaft bag comes with a set of long axles which goes with the oversized hubs from the parts A set. I think this give the car a track width of 190mm. So, this doesn't really require any extra spending.
Basically, I've read that some drivers feel that the car is too narrow and have chosen to use the long axles with the oversized hubs and want to find out more about how prevalent this is with other TT01 racers around.
