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

Pro Tip: The Subaru BRZ, Scion FR-S, and Toyota 86 are the same car — built on the shared ZN6/ZC6 platform developed jointly by Subaru and Toyota. The only differences are badging, trim options, and minor styling. All three share identical suspension geometry from 2012 through 2020, including the 2017 facelift. To confirm your exact model, check the make/model on your registration and the production date on the driver's door jamb sticker.
Q: Does this kit really fit the BRZ, FR-S, and Toyota 86? Aren't they different cars?
A: They are the same car. The BRZ, FR-S, and 86 were jointly developed on the shared ZN6/ZC6 platform. Only differences are badging and minor styling — suspension geometry is identical from 2012-2020. US naming: Scion FR-S (2013-2016) → Toyota 86 (2017-2020); Subaru BRZ throughout. This single kit fits all three.
Q: Will this fit the 2022+ Subaru BRZ or Toyota GR86?
A: No. The 2022+ BRZ (ZD8) and GR86 (ZN8) are an all-new second-generation platform with different suspension geometry. This kit is for first-gen ZN6/ZC6 only (2012-2020). Contact service@flasharkracing.com for second-gen kits.
Q: How low can I drop my BRZ/86 with this kit?
A: The kit provides 1-3 inches (25-75 mm) of lowering from factory ride height via the threaded spring perch. Most owners run 1-1.5 inches — the BRZ is already low from factory. Going to 2-3 inches may require checking tire clearance, camber adjustment, and adds driveway clearance concerns.
Q: Do I need to cut or modify anything to install these coilovers?
A: No cutting or fabrication required. Direct bolt-on replacement for factory struts and rear shocks on all ZN6/ZC6 models. Allow 3-5 hours for a full install on a lift. Professional alignment is required after install.
Q: Are the front camber plates adjustable?
A: No. This kit uses fixed front top mounts — camber is not directly adjustable. For camber correction after lowering, use aftermarket camber bolts or adjustable front control arms (sold separately). The BRZ/86 has limited factory camber adjustment.
Q: Are the dampers adjustable? How do I tune them?
A: No, the dampers are non-adjustable (pre-set fixed valving) — factory-tuned for a balanced street/light-track ride. For adjustable damping, see our Track Series (32-way) coilovers.
Q: What is the spring rate, and why is it softer than other kits?
A: 6 kg/mm (336 lbs/in) front and 5 kg/mm (280 lbs/in) rear 55CrSi springs. Specifically calibrated for the lightweight RWD BRZ/86 platform (~2,756 lbs). Softer than WRX kits because the car is much lighter. Stiffer front / softer rear bias sharpens turn-in and allows rear rotation, matching the 53:47 weight distribution.
Q: What is 55CrSi spring steel, and why is it better?
A: 55CrSi is a chrome-silicon alloy spring steel with high rigidity and excellent fatigue resistance. Cold-bent manufacturing work-hardens the steel for better rate retention and less sag over time vs. hot-wound springs. Commonly used in performance and motorsport coilovers.
Q: Is this kit for RWD or AWD?
A: This kit is for the RWD-only BRZ/FR-S/86 platform. These cars were never offered with AWD. Spring rates and damper valving are specifically tuned for this RWD layout. Do not install on any AWD Subaru (WRX, STI, Impreza).
Q: Do I need an alignment after installing coilovers?
A: Yes — a 4-wheel alignment is required after installation. The BRZ/86 has limited factory camber adjustment; most lowered owners add aftermarket camber bolts. Expect $80-150 at a shop experienced with modified BRZ/86s. Re-check after 500 miles once coilovers settle.
Q: What is the Allen wrench for?
A: The Allen wrench (hex key) is for tightening the set screws / lock bolts on the coilover adjustment collar. After adjusting ride height with the C-spanner wrenches, use the Allen wrench to secure the lock bolt and prevent the collar from loosening during driving. Always re-tighten after any height adjustment.
Q: Will these coilovers fail my state inspection / DMV check?
A: In most U.S. states, coilovers are legal if minimum ride height is maintained (varies by state). The BRZ is already low from factory — we recommend 1-1.5 inch drop for street legality in most states. Check your state's ride height laws. Not DOT/SAE certified — install at owner's discretion.
