Since I went to the square setup, I've only had set full set of rear 8.5" wheels and another half set. This meant that I couldn't swap between tire sets. I finally got another pair of rear wheels but found that I didn't have any more red plastidip to paint them - but I did find several cans of gold!
I've always wondered what gold wheels would look like so I went ahead and sprayed a set. I plan to run the gold wheels at the PCA Festival of Speed in two weeks. The good news is that I can always swap back to red in about an hour.
