Product Description

The Enkei 3798856530SP is an RPF1 lightweight racing wheel in F1 Silver, sized 18x8.5 with a +30mm offset and 5x114.3 bolt pattern. The RPF1 is one of the most iconic and widely respected aftermarket performance wheels ever produced, developed using the same technology Enkei supplies to the McLaren Formula One team. It is manufactured using Enkei's proprietary MAT (Most Advanced Technology) rotary forging process, which reduces weight by 10 to 15 percent compared to conventional casting while maintaining superior structural strength. At approximately 18.3 pounds, the RPF1 significantly reduces unsprung weight, improving handling, acceleration, and braking response. The twin spoke layout is engineered for optimal stress dispersion during hard cornering and braking, while the pocketed center design around the bolt circle adds rigidity and improves heat dissipation under aggressive driving. With a 73mm hub bore and 1,520-pound load rating, this wheel fits a wide range of popular sport compact and performance vehicles including the Mitsubishi Evo, Nissan 350Z, Subaru WRX/STI, and Honda Civic. This is a universal fitment wheel -- buyers should verify offset, brake clearance, and hub bore compatibility before purchase. Hub-centric rings may be required. Center caps are not included with 18-inch RPF1 wheels. Sold individually. Every RPF1 is Spec-E inspected and backed by Enkei's lifetime structural warranty.
