Performance Lightweight Flywheel Kit | Audi B8 S5

An innovative new flywheel option is now available to Audi B8 S4 owners.

The ECS engineered Lightweight Flywheel weighs in at 18.3 lbs versus the factory 29.8lb - a staggering 11.5lbs of weight savings.

A decreased mass means a lower moment of inertia, allowing your engine to rev much more quickly - improving acceleration.

Heat treated and black zinc plated for corrosion resistance and durability, the ECS unit is a model of engineering precision.

For a complete swap, we’ve paired our flywheel with South Bend stage 1 or 2 clutch kits for a considerable performance solution.
