Torque Solution – Lightweight Alternator Pulley – 2022+ Subaru BRZ / Toyota GR86

The Torque Solution Lightweight Alternator Pulley reduces rotating mass to free up power and improve throttle response on the FA24 engine. Factory steel pulleys add unnecessary inertia — by replacing it with a precision-machined lightweight unit, the engine spins more freely, revs quicker, and delivers a sharper driving feel.

This pulley upgrade is a proven motorsport trick for improving performance without altering tuning or reliability. Acceleration becomes more immediate, heel-toe downshifts feel smoother, and the engine feels more eager throughout the rev range. Installation is straightforward and retains OEM belt alignment.
