Historic Motorsport Engineering – McLaren M23 Formula 1 Heritage
The 3SDM F1 M23/6 is a high-performance 1-piece forged aerospace-grade alloy wheel engineered specifically for historic Formula 1, F2, and F3 racing cars. Designed from the original drawings as a period-correct homage to the iconic 1976 McLaren M23 F1 chassis, this wheel delivers maximum structural integrity, ultra-low unsprung weight, and compliance with historic racing regulations. This 4 spoke style was used on pretty much all pre-carbon tubbed race cars from the M2B right up to the M30. The variant shown is the 13×10.0 front wheel, to view the matching rear wheel, click here.
Fully custom-manufactured in the UK from 6061-T6 forged aluminium, the F1 M23/6 is available in widths up to 18J to accommodate wide rear race slick fitments.
For more price sensitive applications, we also make a 3pc version here.
