FMR™ (Forged Monoblok Rim) is HRE’s proprietary one-piece aluminium forged barrel technology. Made with the same process and from the same material as our one-piece wheel forgings, 6061-T6 forged aluminium, it is mated to a forged wheel centre creating the finest 2-piece forged wheel on the market today. The HRE FMR™ barrel offers greater stiffness, reduced mass, higher concentricity and eliminates the air seal required of traditional three-piece wheels.
The S1SC wheels feature aggressive styling similar to the Monoblok P1SC and employ multiple technical design features for increased stiffness and reduced mass. In typical HRE fashion, particular attention was paid to spoke details, including intersection points and the fastener flange surfacing.
