BONOSS History:

For nearly 10 years now, BONOSS is the name after BLOXsport upgrade, it has been the go-to place for aftermarket wheel parts in just about every corner of many countries. With humble beginnings in 2014, BONOSS has developed to become a more influential retailer of all time. BONOSS still focuses on what we believe that quality means words of mouth, we aim to modify every special car with BONOSS productions.

We have provided our products with many cars and received feedback from the distributors and customers. The following feedback was from a Mercedes-Benz AMG A35 customer, he chose a kit of BONOSS forged lightweight plus wheel spacers and proper length of extended bolts. According to the data of Mercedes-Benz AMG A35(W177) we collected before, we recommended installing front and rear 12mm (0.4 inches), PCD 5*112, CB 66.5, ball seat bolts M14*1.5, bolt length 42mm.

What does wheel spacer do?

1.Correcting Positive Wheel Offset

Many customers would like to install some beautiful aftermarket wheels which set up with a positive offset. There is an important thing that should be aware that an excessive positive offset will cause the inner edge of your rims and tires to rub against the suspension components. It can also negatively affect your car’s handling, making it potentially dangerous to drive. In this case, wheel spacers can be the most cost-effective solution. Wheel spacers can create the desired clearance to correct the positive offset by pushing the wheels out from the vehicle hub.

2. Passing Bigger Brake Calipers

Larger brake calipers with more pistons will offer greater stopping power and shorter stopping distances than the OEM ones. In common cases, bigger calipers will take up more room than the stock one, took up the wheel installation area, so that the wheels cannot be mounted back with a proper engagement, leading to vibration and a potential disaster in daily driving. 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, wheel spacers can also be your simplest solution.


3. Flushing Widebody Fenders Postures

In many cases, customers modify the car into widebody posture, a low and wide stance. But you need two wider wheels to fit the fenders. Otherwise, the wheels look like hiding under the fenders. You can’t have a perfect posture for the car. Install the proper thickness wheel spacers to fit the fenders well. Also, in a BMW case, hellaflush style also needs to install the wheel spacers to have a better posture.


Why choose BONOSS Wheel Spacers and Extended Bolts?

BONOSS Wheel Spacers Compared with the previous product before the upgrade, the weight is reduced by about 20% on average, and the lightweight effect is more direct, it is designed with a special “disassembly slot”, easy to remove and install, improve work efficiency. The “knurling” design is used on the cylindrical surface of the wheel spacer, which can effectively increase the contact area with air and increase the cooling effect.

It uses a sealed design to prevent rainwater and debris from entering the shaft head. The price is more reasonable. Although the “Lightweight Plus” causes an additional increase in manufacturing costs, for a better customer experience, we bear this cost and maintain the same price as the previous product before the upgrade.


Completely overturn! Many manufacturers claim that grade 10.9 is a high-level standard for the wheel bolts, but we are manufacturing a higher lever standard of bolts. That is grade 12.9. In addition, we did a lot to make this piece of wheel bolt being extraordinary.

Firstly, the unique 12 petals cornucopia head shape highlights the super forging one-time forming craftsmanship, which can not be presented in a later turning process. Second, we use the best quality material to manufacture it, forged with SCM440 High Strength Steel, better than SCM435, common 35CrMo, and 40Cr in the market. Third, the spacer structure effectively eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxially deviation between hub and shaft head while driving. There are TUV, SGS, and many tests that can prove what we did for a piece of the bolt.


Mercedes-Benz AMG A35

It is an A-Class car which impressive pace, brakes, and overall dynamics. The A35 may be the cheapest car in the AMG range, if you want to try AMG, that might be a cost-efficient choice. While the A35 may not thrill like the most driver-focused hot hatches, it is every bit as fast and capable as the best of them, it provides the same lever delivering a level of technology, luxury, and ride comfort that none of them can rival.

KW V3 Coliovers works good, even when it feels hard to drive over potholes, they still do a good job in damping. KW is known for its Motorsport experience. The performance of the KW V3 is brilliant. Wheel spacers and bolts are a perfect fit for the car, 12mm for the front and rear wheels achieve what customers want, neither too much nor little. The wheels flush with the fenders and the whole appearance of the car is full, not sunken.
