Signal Forged CL18-6 Center Lock Series Forged Wheels
Signal Forged CL18-6 — Center Lock Series Monoblock Forged Wheel
The Signal Forged CL18-6 features an evolved spoke geometry from the CL18, produced as a monoblock center lock forged wheel. Machined from a forged T6-6061 aluminum billet on a HAAS CNC mill, it is manufactured as a single continuous piece — center lock interface, spoke structure, and rim flange all emerge from the same forging. Every CL18-6 is built to customer specification.

Wheel Care
- Clean with a pH-neutral wheel cleaner and a soft microfiber brush. Avoid alkaline and acid-based cleaners — they can etch the brushed and polished finishes used on Signal Forged wheels.
- Rinse with cool water before applying any product, and never spray product onto hot rotors or hot wheel surfaces.
- Apply a dedicated wheel sealant or ceramic coating every 3–4 months to protect against brake-dust etching and UV.
- Torque lug bolts to manufacturer specification and re-check after the first 50–100 km of driving.
- Inspect for curb damage regularly — forged wheels are impact-resistant, but any kerb strike should be checked by a wheel specialist.
