Alu disk RTR Tech 5 20x10.5 "ET45 matt gray for Mustang 2015+

Made with Flow Form technology - the wheel is cast from aluminum and then quenched to maintain flexibility and durability. The casting is then placed in a special machine that heats the wheel while the roller stretches it to the final size of the rim. This expansion improves the structure of the aluminum, making the wheel much stronger but lighter than ordinary aluminum wheels.
