GFB lightweight BRZ/86/FR-S alternator pulley direct replacement is made from aircraft-grade 6061-T6 aluminium and is significantly lighter (and better looking!) than the factory pulley.
Like all GFB lightweight pulley kits, you can feel the improvements:
- Sharper throttle response
- Engine feels more willing to rev
- Stronger ?urge?
(The picture is only a sample!)
