You want to stop, right?: Brake System Upgrades
Brake system upgrades are a popular performance enhancement. Whether it's to improve the appearance of your vehicle after installing open-spoke wheels, to improve stopping ability on the track or to shorten stopping distance for safety's sake, many brake upgrades result in a larger brake system rotor or caliper, or both. While looking good and filling out the space behind the spokes of your wheels, these larger brake system components pose a challenge to the wheel fitment. Original Equipment wheels installed at the factory were not designed with larger brake components in mind, and rarely allow sufficient clearance in diameter and behind the spokes for a performance brake upgrade. The increased diameter of the brake rotor will often dictate using larger diameter wheels, sometimes as much as 2-3" larger. Because the caliper is often changed as part of the upgrade, consideration must be given to the size and shape of the new caliper, which will encroach on the space directly behind the spokes or face of the wheel. The combined shape of the new rotor and caliper create a profile, which must be measured and compared to the space behind the wheel to determine if sufficient clearance exists. But it's important to remember that larger wheel diameter alone does not assure clearance around the brake components. It's the combination of diameter and profile, or shape of the wheel itself, that determine how much room is available for larger brake components.
