ISR Performance Pro Series Coilovers – Scion FR-S / Subaru BRZ / Toyota 86 / GR86 | IS-PRO-FRS

ISR Performance’s Pro Series coilovers for the Scion FR-S (2013–2016), Subaru BRZ (2013–2024), Toyota 86 (2017–2021), and Toyota GR86 (2022+). The Pro Series is ISR’s step up from the Basic line — adding 32-way damping adjustability, pillowball upper mounts with front camber adjustment, and high-end Japanese bearings throughout. A serious street and track coilover for FR-S/BRZ/86 owners who want more adjustability and more precise damping control than the Basic line provides. Engineered for a platform with an already well-regarded stock suspension — the Pro Series builds on that foundation for track day and spirited street use where dialling in alignment and damping matters.

Key Features

• 32-Way Damping Adjustment: 32 levels of damping adjustability — significantly more resolution than typical 16 or 24-way coilovers. Dial from a compliant daily driver setting to a firm track setup without swapping components. The FR-S/BRZ/86 platform responds well to damping tuning, particularly at the rear where oversteer balance is sensitive to rear damping stiffness
• Mono-Tube Construction: Mono-tube shock bodies provide better heat dissipation than twin-tube designs — maintaining consistent damping performance during sustained track use where shock temperatures rise through repeated cornering cycles. The FR-S/BRZ/86 is a popular track day and autocross platform where shock heat management matters
• 8K Front / 6K Rear Spring Rates: Spring rates suited to street and light track use on the FR-S/BRZ/86 — firm enough for responsive handling without the harshness of a dedicated track-only setup. The slightly softer rear rate (6K) relative to the front (8K) helps manage the platform’s natural rear rotation tendency
• Pillowball Upper Mounts with Front Camber Adjustment: Front coilovers include pillowball upper mounts with integrated camber adjustment — allows negative camber to be set beyond the factory adjustment range. Essential for track use where front camber is tuned for maximum cornering grip, and useful for aggressive street alignment. Pillowball mounts transmit more road noise than rubber mounts — an accepted trade-off for the improved steering feel and camber adjustability they provide
• High-End Japanese Bearings: Quality Japanese bearings throughout — smooth operation and long service life under repeated compression and rebound cycling
• ISR Performance: ISR Performance’s Basic coilover line has been used in professional Formula D drifting — the Pro Series is the higher-specification street and track offering built on that same engineering foundation

Fitment

• Scion FR-S (2013–2016)
• Subaru BRZ (2013–2024)
• Toyota 86 (2017–2021)
• Toyota GR86 (2022+)

A four-wheel alignment is required after installation — use the front pillowball camber plates to set front camber as part of the alignment. Pillowball upper mounts transmit more road noise and vibration than factory rubber mounts — expected and normal. A brake bed-in procedure is not required for coilover installation, but confirm all suspension fasteners are torqued to specification before driving. Professional installation recommended. Note: GR86 (2022+) uses the ZN8 platform — confirm fitment compatibility for your specific production date.
