GFB Lightweight Alternator Pulley - Subaru BRZ/Toyota 86 / Scion FR-S (ZC6/ZN6)
GFB has built a name on precision engineered engine ancillaries that shave rotating mass without compromising durability. This lightweight pulley kit is designed specifically for the Subaru BRZ and Toyota 86 (badged Scion FR-S in some markets), giving the flat four a noticeably freer feeling top end. SKU 2221.
This listing covers the Subaru BRZ and Toyota 86/Scion FR-S, chassis ZC6 and ZN6. The kit is supplied as a complete three pulley set rather than a single crank pulley replacement, so the inertia reduction benefit is maximised across the drivetrain.
Key Features
- Machined from 6061-T6 aluminium billet
- Precision CNC machined to tight tolerances
- Black anodised finish for wear resistance and a stealth look
- Combined weight saving of 2.2 kg (77 percent) over the three pulley set
- Rotating inertia reduction of 83 percent
- Sharper throttle response and a more willing rev character
