RPF1 18x9.5 +38mm 5x114.3 73 - SBC

• Universal

The Enkei RPF1 (part 3798956538SBC) is a Racing Series wheel in size 18x9.5 with a +38mm offset, a 5x114.3 bolt pattern and a 73mm center bore, finished in SBC (Special Brilliant Coating). The RPF1 is built with Enkei's MAT (Most Advanced Technology) process, which combines one-piece cast wheel technology with a rim forming (spinning) process to produce a lighter, stronger wheel. This is a universal-fitment wheel — verify your vehicle's bolt pattern, offset and center bore before purchase. This listing is for one wheel.

Features

• MAT (Most Advanced Technology) process combines one-piece cast technology with a rim forming (spinning) process; Enkei states shaping by the MAT process reduces wheel weight by 10%-15%
• Twin-spoke design achieves better stress dispersion on curves, hard braking and extreme race driving
• Pocket design around the bolt circles increases rigidity and keeps the wheel cooler during aggressive race driving
• Spec-E inspected: Enkei's own test standard, tougher than JWL requirements

A: A single wheel. This listing is for one Enkei RPF1 wheel, part 3798956538SBC.

Q: What is the SBC finish?

A: SBC stands for Special Brilliant Coating, the finish applied to this RPF1 wheel.

Q: What is Enkei's MAT process?

A: MAT (Most Advanced Technology) combines one-piece cast wheel technology with a rim forming (spinning) process, and Enkei states that shaping by the MAT process reduces wheel weight by 10%-15%.

Q: What is Spec-E?

A: Spec-E is Enkei's own test standard, which is tougher than JWL requirements: it requires a higher drop point in the impact test and 20% more cycles for the rotary bending fatigue and dynamic radial fatigue tests.
