Go Fast Bits Lightweight Non-Underdrive Pulley Kit (3 pcs) - Scion FR-S / Toyota 86 / Subaru BRZ 13-20

Description

GFB Lightweight Pulleys for BRZ/FR-S/86

Like all GFB lightweight pulleys, these begin life as a single 6061-T6 aluminium alloy billet, which is then precision CNC machined to exacting tolerances. We then anodize them black for a stealthy appearance and superior wear resistance.

This kit is supplied with 3 pulleys, not just for looks - the combined saving of 2.2 kg is significantly more than what is achieved by replacing just the crank pulley alone.

The weight doesn’t tell the whole story either - even though the saving is a significant 77%, the actual rotating inertia reduction (inertia is what counts) is 83%.

Like all GFB lightweight pulley kits, you can feel the improvements:

- Sharper throttle response
- Engine feels more willing to rev
- Stronger “urge"
