The car comes with RC10L parts, so that should be what you have unless it was converted to use 12th scale wheels. The rear hub will have 4 bolts if it is 10th scale. If it has 2 or 3 bolts, it is 12th scale. Either way, you should be able to get greens and greys for the rear and purple up front. Jaco used to make them and there should still be quite a bit available. TRC makes them as well and you can order Calandra Track Magnets from CRC. Corally uses the 10th scale wheels too, so you can use theirs as well. I'd try running the car with foams before trying to make caps. If you have access to a leaf blower, blow off the surface before racing and you should have decent results. If you can, spray some soda on the track with a bug sprayer. It will improve traction and washes off easily with water, so no one should give you a hard time about spraying.
