The CL15 is RM Forged's flagship one-piece monoblock wheel, engineered for enthusiasts and track-focused drivers who want the purity of true center-lock aesthetics without sacrificing the strength and precision of a fully forged structure. Machined from a single billet of aircraft-grade aluminum, the CL15 pairs motorsport-derived proportions with a deep, multi-spoke face that channels the look of exotic center-lock hubs found on marques like Porsche and Ferrari — delivered as a genuine forged 1-piece (1PC) wheel rather than a bolted assembly.

Design & Construction

• Forged 1-Piece Monoblock — the barrel, spoke face, and lip are forged and CNC-machined from one continuous piece of material, eliminating the seams, adhesives, and fasteners found in multi-piece wheels. This yields a stiffer, more fatigue-resistant structure at a significantly lower weight than an equivalent cast wheel.
• Center Lock Design Face — a sculpted, low-profile center cap and single-nut-inspired hub area replicate the visual signature of true center-lock wheels, paired with a directional multi-spoke pattern that adds depth and dimension under changing light.
• Material — forged 6061-T6 aluminum alloy, chosen for its high strength-to-weight ratio and resistance to cracking and fatigue under repeated load cycles.
• Deep Concave / Aggressive Lip Options — available in standard and deep-concave lip profiles for both flush OEM+ fitments and aggressive stance builds.

Performance Benefits

• Reduced Unsprung & Rotational Mass — a lighter wheel improves acceleration, braking response, and steering feel by lowering the mass the suspension and brakes have to manage.
• Superior Strength — the forging process aligns the aluminum's grain structure for greater impact resistance and load capacity compared to cast or flow-formed alternatives.
• Precision Balance — tight manufacturing tolerances minimize runout, contributing to smoother high-speed rotation and reduced vibration.

Specifications

Exact diameter, width, and offset are configured per vehicle application — consult with a fitment specialist to confirm the correct spec for your car.

Finish Options

Available in a range of factory and custom finishes, including Gloss Black, Satin/Matte Black, Brushed Titanium, Hyper Silver, and full custom color-matching to your vehicle's paint code. Each wheel is clear-coated for corrosion and UV resistance.

Fitment & Applications

The CL15 is built to order for high-performance sports cars, supercars, and luxury platforms where center-lock styling is either factory-native or desired as an upgrade — including Porsche 911/718/Panamera, Ferrari, Lamborghini, McLaren, and select Mercedes-AMG, BMW, and Audi performance models. Custom hub bore, offset, and bolt-pattern adapters are available to fit non-center-lock vehicles with the visual center-lock face.

What's Included

Each set ships with wheels, center caps, and valve stems; hardware and lug/center-lock adapters are matched to the specific vehicle application at the time of order.
