Enkei - enk3797856530BK - RPF1 17x8.5 5x114.3 +30 Matte Black Wheel

Enkei RPF1 wheels represent an iconic benchmark in modern motorsport, combining Formula One-derived twin-spoke architecture with ultra-lightweight performance for track cars, sport compacts, and sports sedans. 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.

• Dual-spoke distribution spreads side stresses across two spokes to increase wheel rigidity under heavy lateral g-forces while optimizing brake caliper clearance
• Built to Enkei’s Spec-E testing standard, demanding higher impact drop energy and 20% more rotational fatigue cycles than standard JWL guidelines
• Multi-stage protective surface treatment shields against extreme track heat cycles, road salt corrosion, and brake dust accumulation
• Precision-machined center bore accepts hub-centric centering rings to eliminate high-speed chassis vibration and wheel stud fatigue
• Pocket milling around the bolt circle relieves extraneous weight from the center hub area without compromising structural integrity

The Enkei RPF1 wheel combines Formula One-derived twin-spoke architecture with Enkei’s MAT (Most Advanced Technology) flow-forming process. Designed for track cars, sport compacts, and sports sedans, its lightweight construction helps reduce unsprung mass for responsive acceleration, sharp turn-in, and precise suspension articulation.

Key Features & Performance Benefits

• Dual-spoke architecture: Distributes side stresses across paired spokes to increase rigidity under lateral loads while optimizing brake caliper clearance.
• MAT flow-forming construction: Delivers an exceptional strength-to-weight ratio for performance-focused applications.
• Spec-E testing standard: Tested with higher impact drop energy and 20% more rotational fatigue cycles than standard JWL guidelines.
• Protective surface treatment: Helps shield the wheel against track heat cycles, road salt corrosion, and brake dust accumulation.
