3SDM 3.SLNR90 - Group C Forged, Built for Saloon Racing

3SDM 3.SLNR90 - 3-Piece Forged FR Series Wheel for Closed-Wheel Circuit Racing

3SDM 3.SLNR90 is a 3-piece forged wheel engineered specifically for Group C closed-wheel saloon racing. Where the FR Series street range is configured around road and track-day requirements, the SLNR90 is a competition-focused design built to Group C specification with weight, stiffness, and reliability targets driven by race regulations and endurance load cycles.

3SDM 3.SLNR90 Engineering

The SLNR90 uses the same 3-piece modular build process as the FR range - independently CNC-machined face, inner barrel, and outer rim - but the component specifications reflect racing rather than road use. Face alloy selection, barrel wall thickness, and hardware torque specification are all set to meet the structural demands of circuit racing over race distances, not road miles. Each set is built to the team's exact wheel specification, validated against the car's actual load case.

3SDM 3.SLNR90 Design

The SLNR90 spoke architecture prioritises structural efficiency over visual complexity. Fewer design elements means fewer stress concentration points, and the open face construction maximises airflow to the brake package - a critical factor in Group C competition where brake temperatures are monitored across every stint.

3SDM 3.SLNR90 Vehicle Fitment: BRSCC, Group C Saloon, Circuit Racing

The SLNR90 is specified for BRSCC Group C competitors, club saloon racing series, and closed-wheel circuit programmes where the wheel must meet both regulation and performance requirements simultaneously.
