Enkei - enk3798856530BK - RPF1 18x8.5 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 is a lightweight performance wheel featuring a Formula One-derived twin-spoke design and Enkei’s MAT (Most Advanced Technology) flow-forming process. This 18-inch wheel is finished in black and designed for track cars, sport compacts, and sports sedans.

Key Features & Performance Benefits

• Dual-Spoke Architecture: Distributes side stresses across paired spokes to increase rigidity under lateral loads.
