Change your rims. Yup, you read right - change your rims. Not to any rim, but choose a lightweight alloy rim and get a suitably sized one. Unsprung weight is one of the main factors that affects your cars performance.
Essentially 'unsprung weight' is whatever part of the car that's not supported by the cars suspension, meaning brakes, rims, and tyres, so these parts are susceptible to road shock and cornering forces. Reducing unsprung weight will give you more steering feel and in some cases improve your cornering ability. Also, by getting lightweight rims, you reduce rotational mass therefore improving acceleration and even braking!
A simple example would be my own Wira SE. The Wira SE comes stock with 16" JRD rims and 205/45/16 tyres. That's kinda wide and large (and heavy!) for a car that barely weighs 1.1 tons. After changing to lightweight 4.6kg 15" rims running on 195/55/15 tyres, the car accelerates and brakes better. Changing directions was significantly crispier and faster.
According to some, alloy wheels also help (to some extent) cool the brakes faster because of the heat dissipation properties. I can't confirm or deny this.
