FMR® (Forged Monoblok Rim) is HRE’s proprietary one-piece aluminum forged barrel technology. Made with the same process and from the same material as our one-piece wheel forgings, 6061-T6 forged aluminum, it is mated to a forged wheel center 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.

FMR-X® barrels are available in two lip profile options: Round Lip, and Flange Lip.
The Round Lip matches the profile of traditional 3-Piece lips found on modular wheels with a more broad highlight.
The Flange Lip emulates a motorsport look from traditional 3-Piece lips giving a more lightweight visual look with smaller highlights.
