Better control performance! Yesterday, this Honda Accord 10th installed BONOSS Forged Active Cooling Wheel Spacers, front 15mm (3/5″), rear 20mm (4/5″), PCD 5×114.3, CB 64.1. What do wheel spacers do? By sandwiching between the assembly hub and wheel, they create a gap that sets the wheel away to an ideal distance. This increases the distance between the left and right wheels. A wider wheel track offers better traction, leading to more stability and better handling performance, that is why they are often used on many racing cars. For decoration reasons, wheel spacers give your car a more aggressive exterior as well as a better aerodynamics body. Besides, they are made with modern CNC 0.02mm machinery, ensuring that each wheel spacer fits snugly and securely.
