Are wheel spacers safe for Lexus RX300? How thick Lexus wheel spacers do I need? How to install an AP Racing brake kit safely? For many car enthusiasts who pursue personality and extreme performance, aftermarket wheels and big brakes kits upgrades are the most common beginning modification. Big brake upgrade is one of the most instant and effective modifications for performance cars. Although factory brakes offer enough stopping power for daily commuting, they are actually unable to handle continuous high-speed braking and hard driving in racing events. Performance brake kits help to increase stopping power, enhance heat dissipation, and improve pedal response for shorter braking distances, faster lap times, and safer.

Although upgrading to big brake kits will provide a significant performance increase, they may not always fit stock or aftermarket wheels. In order to accommodate the larger size of performance brake kits, your Lexus RX300 stock or aftermarket wheels often require the installation of wheel spacers 5×114.3. By pushing out the wheel, you can gain the ideal amount of clearance for a bigger brake instead of rubbing against it when mounting back the wheel. Besides, they can also increase body control experience, offering better corner performance, and more stable driving. Aesthetically, they bring the wheels more flush with the fender, providing a more aggressive and powerful stance. (Thanks IG Performance for Supporting.)

Are Lexus Wheel Spacers Good or Bad?

Wheel spacers allow for putting larger brake calipers and pads on for additional stopping power and better handling. Higher-performance brake kits are often bigger than the stock parts. For this Lexus RX300 brake upgrade, 15mm wheel spacers make the required room for installing these AP Racing brake kits that wouldn’t fit in the factory wheel space. They function as AP Racing wheel spacers.  Furthermore, installing wheel spacers helps to increase the distance between the left wheels and the right wheels, hence increasing the traction. With the improvement of the traction, the comfort level of handling the vehicle improves a lot.

What does Active Cooling Design Mean?

There is a special design petal shape grooves that exist on the active cooling wheel spacers. The grooves can make use of the wheel spacers rotation to allow the external cold air to enter and continuously flow inside the wheel spacers through these aerodynamic arcs to take away the heat, so as to achieve the purpose of actively dissipating heat for the braking system. The principle is to rotate like a fan for the braking system, supplying air and reducing heat. Through this way, it can improve braking efficiency, and reduce driving safety risks. BONOSS aims to provide products with more additional functions, safer, higher performance, more professional design, and a friendly experience.
