The twin spokes on the Enkei RPF1 achieve better stress dispersion on curves, hard braking, and extreme race driving. CENTER DESIGN: Enkeis pocket design around the bolt circles increases rigidity and keeps the wheel cooler during aggressive race driving. MAT PROCESS: Shaping by the MAT process reduces wheel weight by 10%-15%. Every pound of unsprung weight savings has the effect of reducing overall vehicle weight by 20lbs.
