RCM Titanium Wheel Nut Set 51220-TA0-A02 HKS GT III turbo isRCM Titanium Wheel Nut Set (x20) Titanium wheel nuts are 29% stronger and nearly 50% lighter than steel which results in a decreased rotational wheel mass, quicker acceleration and handling benefits in high performance applications. Additionally the lower thermal expansion of titanium results in more consistant tension under heating. Super lightweight in design and engineered from aerospace grade titanium these open ended wheel nuts are supplied laser
