Enkei - enk3797106538SP - RPF1 17x10 Silver Wheel, 5x114.3, +38 Offset, 73mm Bore

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
• Pocket milling around the bolt circle relieves extraneous weight from the center hub area without compromising structural integrity
• Precision-machined center bore accepts hub-centric centering rings to eliminate high-speed chassis vibration and wheel stud fatigue

The Enkei RPF1 wheel combines Formula One-derived twin-spoke architecture with Enkei’s MAT flow-forming process to deliver a performance-focused design for track cars, sport compacts, and sports sedans. Its lightweight construction is intended to reduce unsprung mass, supporting responsive acceleration, turn-in, and suspension articulation.

Key Features & Performance Benefits

• Twin-spoke architecture: Dual-spoke distribution helps spread side stresses across the spokes for increased rigidity under lateral loads.
• MAT manufacturing process: Enkei’s Most Advanced Technology flow-forming process is designed to provide a strong strength-to-weight ratio.
• Spec-E testing standard: Built to a testing standard described as requiring higher impact drop energy and 20% more rotational fatigue cycles than standard JWL guidelines.
• Performance-oriented detailing: Pocket milling around the bolt circle removes material from the center hub area while maintaining structural integrity.
