There is little point in upgrading the power of your car without addressing the issue of getting it to stop, so we have developed a range of braking upgrades for the Corsa VXR & SRI to suit both driving type and level of performance. Its worth pointing out that braking performance should not be measured why whether or not you can lock the wheels up or not, that’s like comparing how fast a plane is by how hard it hits the ground if it crashes, it’s a question of power, consistency and longevity.

Braking is all about generating the maximum amount of friction whilst limiting heat, now this is a tough ask as more friction = more heat so all brake upgrades relate to maximising one whilst controlling the other.

Mintex 1144 Fast Road Brake Pads, Braided Brake Hoses, AP Racing DOT 5.1 Fluid


We have developed these pads with Mintex for both road and track use. The standard Corsa pads are pretty good but once you start to use them repeatedly they get very hot and lose performance quite quickly. These Mintex pads have been designed to give greater overall performance, a much better consistency as higher speed braking and excellent resistance to fade. They must be fitted to both axles at the same time (you cant be all pikey and just fit them to the front).

Changing the brake pads to higher specification items is always the first step in improving braking but things can be improved in the rest of the braking system just as effectively. The Corsa comes as standard with rubber brake lines, these deform and flex when in use which cause the brake fluid inside to heat up and reduce braking performance immediately. You hear of people saying the ‘boiled the brake fluid’ well this in part is due to brake lines flexing and heating up the fluid. Following extensive development on our own SRI Corsa race car we have developed special braided brake lines for the car. Braided lines are hoses wrapped in a metal sheath that resists flex and thus reduces the heat build up for the fluid, it means braking consistency is maintained and you have full power braking for longer, especially in repeated braking. Price includes front and rear kits and fitting includes the use of up rated AP Racing 5.1 racing brake fluid.
