This is all possible with the new GTR wheels from CRC. These new wheels are designed for rubber tire 1/10th scale pan car racing, both oval and road. They are direct bolt on for 1/10th cars. In the rear, they use the standard 4 bolt mounting pattern commonly used in oval and World GT. In the front, they use the normal 5/16" OD flange bearing, again very common among the 1/10th oval and World GT cars. The mounted tires measure around 2.45" diameter, most all pan cars can be adjusted to make the proposed 5mm ride height rule.
