GFB 2016 Lightweight Pulley Kit
BRZ/86
Description
GFB lightweight pulley kits are made from aircraft-grade 6061-T6 aluminium and offer faster acceleration through significant weight reduction on the crankshaft.
Most of our kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses. GFB pulley kits are designed to improve acceleration by reducing the rotational mass (inertia) on the crankshaft as well as parasitic loads from the driven accessories. The effect is similar to a lighter flywheel, and the engine feels more lively and willing to rev.
We know that people are sometimes concerned about possible adverse effects of lightweight pulleys and underdriving, but rest assured we have done our homework! The underdrive ratios have been optimised to ensure there are NO adverse effects on the performance of the accessories, and whilst it is true that some engine types do suffer harmonic issues from lightweight pulleys, we steer clear of those. The kits we release are thoroughly application tested and do NOT cause engine damage in the short or long term.
GFB Lightweight Pulleys for BRZ/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”
Lightweight Pulley Kit for BRZ/Scion also suits:
TOYOTA 86 (ZN6) GT-GTS 12-On
SUBARU BRZ MY12-On
