1. Better tire options for 18" wheels.
2. Weight reduction, although the wider wheels most of us run end up bringing the weight back up.
3. Rotational inertia is better on 18" wheels.
4. Even with 315/30-18's on my car I still redline around 67mph which is plenty for most courses to not need 3rd gear.
