[CSanto]

I want to know from current SC owners what other aspects of the car they believe are crucial to upgrade when doing a SC. Assume middle of the road 575 or 600 kit.

I'm assuming wider rims and tires will help with traction.
Coil-overs or some suspension setup will help keep the car planted under hard acceleration.
A BBK will help stop the car from speeds you wouldn't reach as quickly sans the charger.

All these things will no doubt help, but whats necessary? What does the car fail to do well with the extra power?
