After giving serious consideration to paint or powder I decided to go with new allow wheels. I called Cary Hinds first; he did not have 4 bolt alloys, but advised me where to buy them. Mobelwagen.com has numerous and sundry wheels for these here plastic cars. The cost is about $200 each and $40 shipping for the lot. After putting the pencil to the options; alloy's seemed the thing to do.
The wheels are really nice 10 holers...but they don't just bolt on to 4 bolt hubs with disc brakes. Shims are required a pair is about $100 so $200 for the car. I bought 5/16" cast aluminum and will make the shims so I'm not rolling yet. Maybe this week.
