Cusco GR86 / BRZ Lightweight Flywheel

Overview

The Cusco Lightweight Flywheel is a high‑performance, precision‑engineered upgrade designed specifically for the 86/BRZ platform. Built for enthusiasts who demand sharper throttle response, quicker engine revs, and a more engaging driving experience, this flywheel represents a substantial improvement over the stock OEM component.

Crafted from high‑quality SCM435H chromium molybdenum steel, the Cusco flywheel delivers a superior strength‑to‑weight ratio and exceptional durability. Its weight is reduced to approximately 4.8 kg (10.4 lbs) — about 48 % lighter than the factory flywheel—resulting in significantly lower rotational mass and inertia.

This lightweight unit maintains drivetrain balance even at lower RPMs and is engineered to withstand the rigors of spirited driving and track use. While most noticeable in tuned or performance‑oriented builds, many enthusiasts appreciate the livelier feel and enhanced rev‑up characteristics that this flywheel delivers.
