The benefits of lighter wheels (see this month's Fast Ford).

1. Improved acceleration.
2. Improved braking with reduced stopping distance.
3. Greater fuel efficiency.
4. Lighter, sharper steering.
5. Allows for softer damper settings giving more tyre contact & therefore better grip.
6. Tyre temperatures are more stable and generally lower.
7. Improved wheel & tyre balancing.
8. Reduced rim weight has the effect of at least 5 times the static weight reduction.

Summary:
The performance gain achieved by reducing the wheel mass (Un-sprung Mass) can be quantified using a factor of six. This means that to achieve the same performance gain by reducing the body mass, it is necessary to remove six times the wheel weight saving.
Example:
A saving of 2Kg Per Wheel x 4 Wheels = Removing 48 Kg from the Bodywork.
