Lightweight Flywheel
A lightweight flywheel is a lighter replacement flywheel that lets the engine rev up and down faster.
What is Lightweight Flywheel?
It is usually a single-mass design replacing a dual-mass flywheel. It improves throttle response and rev matching. It is common in motorsport and tuning. Replacing a dual-mass flywheel with a single-mass one is common when the original wears out on tuned cars.
How it works
Less rotating mass needs less energy to change speed.
Why it matters for your car
It can increase vibration, gear rattle and stalling in traffic. Fitting one without the matching clutch can cause problems.
