Enkei 4417700145SP RPF1 17x7 5x114.3 +45mm Silver Alloy Wheel

The Enkei RPF1 is one of the most celebrated lightweight performance wheels in the aftermarket world, and this 17x7 fitment in a classic Silver finish with a 5x114.3 bolt pattern and +45mm offset delivers that same race-proven engineering to a wide range of sports cars and performance sedans.

Built using Enkei's proprietary MAT (Most Advanced Technology) process, the RPF1 combines one-piece cast construction with a flow-forming rim technique. This spin-forming method compresses and stretches the aluminum barrel under heat and pressure, aligning the grain structure for forged-like strength at a significantly lower weight — and price — than traditional forged wheels.

Key Features:

• Size: 17x7 inches
• Bolt Pattern: 5x114.3
• Offset: +45mm
• Center Bore: 73mm
• Finish: Silver Paint (SP)
• Construction: MAT flow-formed one-piece aluminum alloy
• Twin-spoke design engineered for superior stress dispersion under hard cornering and braking
• Pocket design around bolt circles increases rigidity and aids brake cooling during aggressive driving
• MAT process reduces wheel weight by 10–15% versus conventional cast wheels
• Meets Enkei's own Spec-E internal test standard — stricter than JWL requirements, including 20% more cycles in rotary bending fatigue and dynamic radial fatigue tests
• Lifetime structural warranty — Enkei guarantees all wheels against defects in materials and workmanship under normal use

The RPF1's clean 12-spoke twin design has made it a favorite among autocross competitors, track day enthusiasts, and street performance drivers alike. Whether you're chasing lap times or simply want a lightweight, durable upgrade over your factory wheels, the Enkei RPF1 delivers proven performance backed by decades of motorsport development.
