HRE Performance Wheels S107 (2-Piece) - Series S1 Five-Spoke Architecture in the FMR-X Weight-Optimised Format

Series S1: Five Clean Spokes with Minimum Rotational Mass in the FMR-X Two-Piece Forged Platform

HRE Performance Wheels S107 (2-Piece) is a 2-piece forged wheel applying the S107 five-spoke geometry to the FMR-X modular barrel format in a configuration optimised for platforms where unsprung and rotating mass are primary design constraints. The S107 spoke count - the minimum in the Series S1 range - reduces forged material at the centre, and the FMR-X barrel format maintains this low-mass philosophy at the outer diameter by eliminating the second set of inner barrel fasteners required in a three-piece assembly. The result is a Series S1 variant built for track-focused road cars and performance platforms with strict weight requirements. Machined in California, USA.

HRE S107 (2-Piece) Design and Engineering: Spoke Economy, Brake Clearance, and FMR-X Efficiency

Five radially arranged spokes define the S107 face. Each spoke tapers from a wider root at the hub to a narrower profile at the rim junction, creating linear taper that contributes to spoke stiffness per unit mass. The large open windows between spokes provide generous brake clearance for oversized caliper packages - a practical benefit on Porsche GT3 RS, Lamborghini Huracan STO, and other track-biased fitments where 380 mm or larger rotors are standard. The FMR-X barrel joins directly to the forged centre using a precision-machined interface and permanent fasteners, producing an assembly with no internal barrel bolts visible through the spoke apertures.

HRE S107 (2-Piece) Technical Specifications

Construction: 2-Piece FMR-X forged modular (forged centre, modular outer barrel). Material: Forged aluminium alloy. Available in 19- to 24-inch diameters. Custom widths and offsets per vehicle. OE TPMS compatible. Lifetime Structural Warranty, 2-Year Finish Warranty. Made in California, USA.

HRE S107 (2-Piece) Available Finishes

The S107 (2-Piece) is available in all HRE standard finishes. The open five-spoke face directs significant attention to the barrel region, making barrel finish selection particularly important. Polished or brushed barrel finishes provide a clean contrast to the spoke faces; dark barrel finishes create a deeper more recessed appearance. Two-tone programs (centre vs barrel) available on request.
