Enkei 3797858030BK RPF1 17x8.5 Black Aluminum Wheel 5x114.3 30mm Offset

The Enkei RPF1 is one of the most iconic and best-selling aftermarket performance wheels ever produced. Available here in a 17x8.5 size with a Black finish, this wheel combines race-proven engineering with a clean, lightweight multi-spoke design that suits a wide range of sport compact and performance vehicles.

The RPF1 is manufactured using Enkei's proprietary MAT (Most Advanced Technology) process, which combines one-piece casting with a rim-spinning (flow-forming) technique. This process compresses and strengthens the aluminum alloy in the barrel, resulting in a wheel that is significantly lighter and stronger than conventional cast wheels—without the cost of full forging.

Key Specifications:

• Size: 17x8.5
• Finish: Black
• Bolt Pattern: 5x114.3
• Offset: 30mm
• Construction: MAT (Most Advanced Technology) flow-formed aluminum alloy
• Testing Standard: Enkei Spec-E — exceeds JWL and VIA requirements

Enkei's proprietary Spec-E testing standard goes beyond the JWL requirement, demanding a higher drop point in impact testing and 20% more cycles in rotary bending fatigue and dynamic radial fatigue tests. This rigorous standard ensures exceptional durability and safety confidence in real-world and track conditions.

The RPF1's minimalist spoke design was originally developed with input from Enkei's motorsport programs, including Formula 1, WRC, and Super GT. It remains a top choice for track day enthusiasts, autocrossers, and performance street drivers who demand a lightweight, strong, and visually timeless wheel.
