Enkei 3798856540BK RPF1 18x8.5 5x114.3 +40mm Black Alloy Wheel

The Enkei RPF1 is one of the most iconic lightweight performance wheels ever produced, and part number 3798856540BK brings that legacy to an 18x8.5 fitment with a 5x114.3 bolt pattern, +40mm offset, in a Gloss Black finish. Developed directly from Enkei's motorsport engineering program, the RPF1 has become the benchmark for track-day and performance street wheels worldwide.

Key Features:

• MAT (Most Advanced Technology) Process: Flow-forming spins and compresses the barrel under heat and pressure after the initial cast, producing a grain structure closer to a forged wheel for superior strength at reduced weight
• 18" x 8.5" Diameter and Width: Ideal sizing for fitment with high-performance tire profiles on sport sedans, coupes, and track builds
• 5x114.3 Bolt Pattern: Broad compatibility with popular sport vehicles across multiple manufacturers
• +40mm Offset: Provides proper flush fitment for a wide range of OEM and modified suspension setups
• Gloss Black Finish (BK): Clean, aggressive aesthetic that complements both stock and modified vehicle appearances
• Lightweight One-Piece Cast Construction: Engineered to minimize unsprung rotational mass for improved acceleration, braking, and handling response
• Racing-Proven Design: The RPF1 platform has been validated in Formula 1, WRC, Japan GT Championship, Formula Drift, and Super Taikyu competition
• JWL and VIA Certified: Meets Japanese rigorous industry standards for structural integrity and safety

The Enkei RPF1 in Gloss Black is a versatile performer that delivers measurable handling improvements over heavier OEM wheels while offering a timeless, motorsport-inspired aesthetic. Sold individually.
