Enkei 3795804928F1B Lightweight Racing Wheel - RPF1 15x8 4x100 28mm Black

The Enkei RPF1 is one of the most iconic lightweight performance wheels ever produced, born from Enkei's role as an official supplier to the McLaren Mercedes Formula One team. The RPF1's twin-spoke architecture draws directly from F1 race wheel engineering, delivering exceptional strength-to-weight performance for track and street use alike. This specific fitment is sized 15x8 with a 4x100 bolt pattern and +28mm offset, finished in Black.

MAT Technology (Most Advanced Technology):

The RPF1 is manufactured using Enkei's proprietary MAT process, which combines one-piece cast wheel technology with a rotary rim-forming spinning process. This hybrid approach compresses and shapes the aluminum alloy barrel to dramatically improve material elongation and structural integrity — reducing wheel weight by 10–15% compared to conventional cast wheels — without sacrificing hardness or durability.

Key Features:

• Twin-Spoke Design: Dual open-stance spokes modeled after Enkei's McLaren Mercedes F1 race wheel, engineered for superior stress dispersion during hard braking, aggressive cornering, and extreme race driving
• Pocket Center Design: Enkei's signature pocket design around the lug bolt circles increases wheel rigidity and improves brake cooling airflow during track and spirited driving sessions
• MAT Process Construction: Rotary forged aluminum alloy barrel reduces weight by up to 15% vs. traditional cast wheels, improving acceleration, handling, and steering response
• Spec-E Inspected: Every RPF1 undergoes Enkei's proprietary Spec-E quality testing, which exceeds JWL standards — requiring a higher impact drop point and 20% more fatigue test cycles
• Lifetime Structural Warranty: Enkei backs every RPF1 with a lifetime structural warranty against defects in materials and workmanship under normal use
• Size: 15x8 | Bolt Pattern: 4x100 | Offset: +28mm | Finish: Black
• Center cap not included (no cap available for 15-inch wheels)
• Includes valve stem and Enkei stickers

The Enkei RPF1 is equally at home on the autocross course, road course, or daily commute. Its clean six-spoke aesthetic, proven race heritage, and class-leading weight make it a perennial favorite among performance driving enthusiasts.
