Originally developed in collaboration with the McLaren Honda F1 team, the RPF1 utilizes Enkei’s MAT (Most Advanced Technology) flow-forming process to yield an exceptional strength-to-weight ratio, dramatically reducing unsprung mass for blistering acceleration, razor-sharp turn-in, and precise suspension articulation.\n\u003cul\u003e\n  \u003cli\u003eDual-spoke distribution spreads side stresses across two spokes to increase wheel rigidity under heavy lateral g-forces while optimizing brake caliper clearance\u003c\/li\u003e\n  \u003cli\u003eBuilt to Enkei’s Spec-E testing standard, demanding higher impact drop energy and 20% more rotational fatigue cycles than standard JWL guidelines\u003c\/li\u003e\n  \u003cli\u003eMulti-stage protective surface treatment shields against extreme track heat cycles, road salt corrosion, and brake dust accumulation\u003c\/li\u003e\n  \u003cli\u003ePrecision-machined center bore accepts hub-centric centering rings to eliminate high-speed chassis vibration and wheel stud fatigue\u003c\/li\u003e\n  \u003cli\u003ePocket milling around the bolt circle relieves extraneous weight from the center hub area without compromising structural integrity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Enkei RPF1 wheel combines Formula One-derived twin-spoke architecture with lightweight performance for track cars, sport compacts, and sports sedans. Its MAT (Most Advanced Technology) flow-forming process is designed to provide a strong strength-to-weight ratio, helping reduce unsprung mass for responsive acceleration, turn-in, and suspension articulation.\u003c\/p\u003e\u003cp\u003eKey performance features include dual-spoke distribution to spread side stresses across paired spokes, pocket milling around the bolt circle to reduce weight in the center hub area, and a precision-machined center bore designed to accept hub-centric centering rings. The wheel is built to Enkei’s Spec-E testing standard, which calls for higher impact drop energy and 20% more rotational fatigue cycles than standard JWL guidelines. A multi-stage protective surface treatment helps shield the finish against track heat cycles, road salt corrosion, and brake dust accumulation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Product Specifications \u0026amp; Technical Data:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWheel model: RPF1\u003c\/li\u003e\n\u003cli\u003eWheel diameter: 18 inches\u003c\/li\u003e\n\u003cli\u003eWheel width: 8 inches\u003c\/li\u003e\n\u003cli\u003eBolt pattern: 5x112\u003c\/li\u003e\n\u003cli\u003eOffset: +35 mm\u003c\/li\u003e\n\u003cli\u003eHub bore diameter: 73 mm\u003c\/li\u003e\n\u003cli\u003eFinish: Silver\u003c\/li\u003e\n\u003cli\u003eConstruction: Cast\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat’s Included:\u003c\/strong\u003e One Enkei RPF1 wheel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Fitment data was not provided.
