Coming from Exotek are their new Shimizu tyre adapter rings for the 3Racing FGX foam tyre wheel sets. The all CNC-machined delrin adaptor rings allow mounting of Shimizu F104 and Tamiya TCS F104 tyres onto the FGX foam wheels. The must have for carpet and cool weather racing allows the use of softer high grip compounds on the FGX. The rings are simply glued into place on the wheels and thereafter allows perfectly true mounting of the Shimizu F104 tyres onto the wheels. The adaptor set includes four rings, usable on the front of the rear rims with two sets being needed to outfit a complete set of wheels.
