Product Specifications
Built for the entire first-generation Subaru BRZ, Scion FR-S, and Toyota 86 family (ZN6/ZC6 chassis, 2012-2020), this Street Series coilover kit delivers the balanced, playful handling that the platform was designed for — with a full stealth black aesthetic that disappears behind your wheels for an OEM+ look.
The twin-tube damper paired with 55CrSi cold-bent coil springs (6 kg/mm front / 5 kg/mm rear) is calibrated specifically for the BRZ/86 platform's lightweight RWD layout and near-perfect 53:47 weight distribution. The slightly stiffer front / softer rear bias sharpens turn-in while allowing the rear to rotate when you want it to — exactly what a driver's car should do. Drops your car 1-3 inches from factory ride height via the threaded spring perch.
The black anodized shock body with anti-corrosion coating blends into the wheel well for a clean, understated look — no flashy accent colors, just performance. 55CrSi chrome-silicon alloy steel springs resist sag and maintain their rate over tens of thousands of miles. Fits all ZN6/ZC6 coupes (2012-2020) — BRZ, FR-S, and 86 share identical suspension geometry across all model years and trims. Not compatible with the 2022+ second-generation BRZ/GR86 (ZD8/ZN8).
Key Features
Stealth Purple Anodized Shock Body — Purple and black-on-aesthetic; anodized finish with anti-corrosion coating for winter/salt durability; OEM+ look that doesn't scream "aftermarket"
1-3 Inch Adjustable Lowering Range — Threaded spring perch lets you dial in the exact stance; drops from factory ride height
Twin-Tube Damper System — Longer stroke and smoother ride than mono-tube; reduces joint pressure and minimizes friction for comfortable street driving
55CrSi Cold-Bent Coil Springs — High-rigidity chrome-silicon steel springs; 6 kg/mm front / 5 kg/mm rear, calibrated for the BRZ/86 lightweight RWD platform
RWD-Tuned Spring Balance — Slightly stiffer front / softer rear bias sharpens turn-in and allows rear rotation; matches the platform's 53:47 weight distribution and low center of gravity
Anodized Shock Body with Anti-Corrosion Coating — Protects against road salt, winter chemicals, and moisture; year-round daily driver durability
Direct Bolt-On Replacement — No fabrication, no cutting; uses factory mounting points on all ZN6/ZC6 models (BRZ, FR-S, 86)
1-Year Manufacturer Warranty — Backed by Flashark's quality guarantee; email service@flasharkracing.com for support
Full Hardware Kit Included — 2 C-spanner adjustment wrenches, 1 Allen wrench, and all pictured mounting hardware in the box
