HotRace foam donuts for 2wd and 4wd rear.
The HotRace buggy foam provides great feeling on track with a very long life. Together with Nicola at HotRace we tested different compounds to find the best balance between tire wear and drivability. The donuts are pre-cut in a width to fit 2wd & 4wd rear wheels.
Diameter when mounted approx 80mm.
