DESIGN AND FEATURES
Cast13’s RB4 features an aggressive, mesh-spoke design and has been engineered with a concave face, more noticeable in the wider sizes. The RB4's thick stepped outer lip design helps compliment the smooth lines of the wheel. The hidden valve in the barrel gives a smooth un-cluttered look and being load rated to 700kg can be used on road cars or track vehicles.
The RB4 is finished in impact silver paint and lacquered for cutting edge looks. The thick stepped lip is machine polished for a high-ended, two tone finish. The RB4 also features our unique signature 3D chrome centre cap.
All Cast13 wheels are subjected to the highest standards in manufacture, finish, testing and quality control, meeting ISO9001 standards and have been JWL (Japan Light alloy wheel standard) and VIA (Vehicle inspection Association of Japan) approved.
