BONOSS Forged Active Cooling Wheel Spacers for Audi S5

BONOSS Forged Active Cooling Wheel Spacers for FordAlthough automakers do require their suppliers to comply with specific standards for quality and performance, these standards are often not good enough for discerning consumers. Therefore, many car enthusiasts choose to upgrade from the original equipment manufacturer (OEM) parts. There are many advantages of improving the braking performance of your vehicle, such as increasing stopping power and reducing brake fade. But a higher-performance braking system means bigger brake calipers. You may meet the rubbing problem between wheel and calipers.

Will wheel spacers keep my wheels from rubbing the brake calipers?

The brake caliper is one of the most essential components of the braking system. It consists of brake pads and an internal piston that applies pressure to the brake pad. When you step on the brake pedal, the pressure will force the brake fluid into the piston, forcing the brake pads against the rotor, hence slowing down the vehicle and heat is created. Larger calipers with more pistons and larger brake pads will offer greater stopping power and shorter stopping distances than the smaller ones. And bigger rotors also radiate more heat from the larger surface areas. More pistons equal more force. In short, larger calipers can stop your car quicker on the road and provide a more enjoyable and dynamic control.

If you have upgraded your brake system with bigger brake calipers and still want to keep the current wheels attached to your vehicle without scratching, you can use a set of wheel spacers. Wheel spacers are a kind of wheel accessories which are used to create necessary distance on the inner portion of the wheel for clearance problem with brakes, tie rods and other suspension components. By pushing out the wheel, you can gain the ideal amount of clearance for a bigger brake caliper instead of rubbing against it when mounting back the wheel.

Additional function for reducing brake fade

High heat will affect the performance of your brake system. One of the main reasons for heat creation in a braking system is to convert the engine stopping power into waste heat. In that case, more friction and stopping power means higher heat. Excessive heat, as we learned, is the enemy of stopping effectiveness, the heat must be dispersed. If the brakes grow extremely hot, and the heat cannot escape from the brakes, your braking system will trend to damage, discounted performance, and finally leading to failure. There is a specially designed heat dissipation grooves structure that exists on the BONOSS forged active cooling wheel spacers. The grooves can make use of the wheel spacers rotation to allow the external cold air to flow efficiently and continuously inside the wheel spacers to take away the heat, so as to achieve the purpose of actively dissipating heat for the braking system. Through this way, it can improve braking efficiency, and reduce driving safety risks. Here are five main features:

1. The grooves are distributed in petal shape, which allows multiple grooves to work at the same time, improving the heat dissipation efficiency greatly.
2. The grooves are designed with an aerodynamic arc, which is conducive to the rapid flow of air and further boosts the heat dissipation function.
3. The grooves are symmetrical design, no matter it is on the left or right wheel, whether driving forward or reversing, the purpose of heat dissipation can be normally and effectively achieved.
4. The grooves applied sealed design, not passing through the center hole, meaning it is capable to prevent rainwater or debris from entering the axle-spacer-wheel connection.
5. Each edge of the grooves is carved with funnel-shaped notches, acting as air collectors which tremendously enlarges the airflow, enhancing the heat dissipation effect.
