BC Racing HM Series Coilover System (2013 - 2025 BRZ / FRS / 86 - ZC6 / ZD8 / ZN6 / ZN8) - F-20-HM
Inverted High-Performance Coilovers for BRZ, FR-S & GR86
Bring elite suspension control to your 2013 - 2025 Subaru BRZ, Scion FR-S, or Toyota 86 / GR86 (ZC6 / ZD8 / ZN6 / ZN8) with the BC Racing HM Series Coilover System. Engineered by blending the top attributes of the RM and ER Series, the HM Series features fully inverted mono-tube dampers for increased structural rigidity and reduced unsprung weight, paired with independent 30-way compression and rebound adjustment for maximum tuning precision. With external reservoirs, steel-braided reservoir lines, and Swift Springs included standard, this system is built for drivers who demand consistent performance - whether carving corners, hitting autocross events, or pushing hard on the track.
Performance Highlights

FAQs
How does the HM Series compare to the ER Series?
The HM Series offers the same independent damping control as the ER Series but features an inverted mono-tube design that improves rigidity and reduces unsprung mass - ideal for McPherson-strut applications.
Do HM Series coilovers come with Swift Springs?
Yes. Swift Springs are included standard for improved response, reduced sag, and better long-term performance.
Are these coilovers good for daily driving?
Yes. The HM Series can be softened for a compliant daily ride or stiffened for competitive performance thanks to its broad damping range.
Can I request custom valving for my spring rate setup?
Absolutely. BC Racing offers custom valving tailored to your preferred spring rates or driving style.
