Increasing the disc outer diameter diameter is one of the easiest ways to increase braking performance drastically. All you need is a bigger disc and a bracket that relocates the standard brake caliper to work with that bigger disc. Alternatively you can go for High Performance brake calipers that are designed for the larger diameter discs. Discs are sold each, caliper relocation brackets must be ordered separately. It is strongly recommended to install new brake pads with a new brake disc.
