The MR13 carries the same forging pedigree as the rest of RM Forged's 2-piece lineup, built around a bolder, more aggressive face design for owners chasing a deeper concave look without stepping away from true forged strength. Like every wheel in the range, it starts as a solid billet of aircraft-grade aluminum, compressed under extreme pressure to align the metal's grain structure — the same process used in motorsport and OEM performance wheels, producing a part that's both lighter and stronger than any cast or flow-formed equivalent.

Construction

The MR13 is built as a true 2-piece: a forged monoblock face bolted to a separately forged barrel, joined with grade 8 stainless hardware and a fully sealed lip joint. Splitting face and barrel lets RM Forged tailor the MR13 to nearly any width, offset, or backspacing without redesigning the wheel — so the same aggressive face can be run in a modest daily-driver width or pushed into an extreme deep-dish fitment for show cars.

• Material: Forged 6061-T6 aluminum alloy, solution heat-treated and aged for strength-to-weight performance
• Construction: 2-piece — forged monoblock face bolted to a forged (or optional stamped) barrel
• Weight savings: Roughly 30–40% lighter than a comparably sized cast wheel
• Hardware: Stainless steel assembly bolts with a weather-sealed barrel joint

Sizing and Fitment

Built to order rather than off a fixed size run:

• Diameters: 18" to 24"
• Widths: 8.5" to 13", staggered front/rear widths available
• Bolt patterns: Custom-drilled to your vehicle's spec, including multi-pattern drilling
• Offset: Set to your specified offset/backspacing for a clean, rub-free fit
• Centerbore: Hub-centric rings included for a vibration-free fit

Finishes

• Gloss or matte black
• Brushed, polished, or chrome aluminum
• Custom powder coat, including candy and pearl colors
• Two-tone face/lip combinations
• Optional forged carbon fiber center cap

Performance Benefits

• Lower rotational mass improves throttle response, braking, and steering feel
• Higher structural strength from forging allows thinner spokes and a more aggressive profile without compromising integrity
• Improved heat dissipation for spirited driving and track use
• Corrosion-resistant finish suited to daily use in all climates

Warranty and Support

Backed by RM Forged's structural warranty against manufacturing defects, with barrel, hardware, and refinishing support available since the wheel is built and serviced in-house.
