On average, BONOSS 20mm spacers weigh only about 1 lb (447g) each and feature a hollowed design for an extra lightweight advantage. Adding such a small lightweight component wouldn’t noticeably slow a car down. In other words, they will not affect the acceleration significantly. For those who pursue extreme performance, this is good. Because the less weight to control, the greater handling and better engine efficiency.

The hollowed hole is a proven design that is effectively reducing weight, achieving a balance between high performance and environmental protection on the premise of ensuring safety and reliability. The average weight of each 20mm spacer is more than 30% lighter than the previous-gen product. If you are looking for wheel spacers with durability and lightweight, then BONOSS aluminum 20mm spacers are the best option.

Will 20mm Spacers Cause Uneven Tire Wear?

20mm spacers are used purely for fitment and aesthetics. They simply serve as the extension parts of the vehicle assembly, so there is no extra force that applies to the tire when installing a spacer. As long as your vehicle has more than a 20mm (0.75 inches) wheel gap, they will not cause any uneven tire wear. Of course, you could have a wheel alignment at the same time which would effectively avoid excessive tire wear.

Since every vehicle is different, it is recommended to take check the tires after installing 20mm spacers. Park the car on flat ground, rotate the steering wheel to one extreme position, and inspect the wheel well of the tire that’s outside. If there is a rubbing, you will notice clear signs on the internal fender and the liner. If there is no tire rubbing, there will be no uneven tire wear, too.

What 20mm Spacers Are Better?

Vehicle-specific 20mm spacers are safer and more reliable. They are precisely machined to your vehicle specification, which ensures perfect wheel fitment. Most of them are hub-centric. Sometimes, manufacturers will make adjustments to the spacers according to the actual characteristics of the vehicle hub assembly. For example, BONOSS 20mm spacers are multi-stage hub-centric. They are designed to perfectly fit your vehicle hub, ensuring there is no vibration.

Precision is important in manufacturing 20mm spacers. In short words, the higher the precision, the better the performance. BONOSS wheel spacers are CNC machined, precision at 0.02mm tolerance. This makes them easier to sit flush up against the vehicle hub and wheel. So, there’s no obvious gap between them. Since 20mm spacers are components that contact with other parts, you absolutely need tight-tolerance ones.
