Reflex Racing's Replacement/Upgrade "Speed Dish" Race wheels feature: performance and durability, molded, with glass reinforced nylon...these wheels come with a ,05 outer ridge (lip) that matches the inner flange of most 1/28 scale wheels, resulting in a tire that is easier to glue which is what Reflex Racing recommends and also more stability to the tire, in the case you prefer to tape the tire. Aceton safe & re-usable, the tall aspect of these wheels...makes the sidewall effectively smaller in order to also aid in the increase of cornering speed. Available in Grey, White & Yellow
