15mm 2023 Audi A4 wheel spacers are one of the common thickness options used, just like the 1-inch offroad wheel spacers used on off-road models. The difference is that the 15mm 2023 Audi A4 wheel spacers are more often used to solve the clearance problem for brake and cosmetic upgrades. The larger wheel spacers provide more space, but for sedans with a stock offset of 30-40, the 15mm 2023 Audi A4 wheel spacers are a very suitable choice.

Are 15mm 2023 Audi A4 wheel spacers safe? Do I need longer wheel bolts to install 15mm 2023 Audi A4 wheel spacers, and how do I ensure that 15mm 2023 Audi A4 wheel spacers stay in place? How to eliminate the shaking problem that may occur when the car is driven at high speed? These common wheel spacers safety questions will be answered below, and we hope you will choose the right product after understanding the real wheel spacers.

Are 15mm 2023 Audi A4 Wheel Spacers Safe?

The 15mm 2023 Audi A4 wheel spacers are of slip-on construction. The center holes of the wheel spacers are aligned and slid into the hub assembly. It is recommended to use the wheel hanger to fix the position of the bolt holes and then put them on the wheels. The extended wheel bolts will go through the bolt-hole thread engagement to lock all the parts. The advantage of the wheel spacers is that they are not subjected to force. The extended wheel bolts take most of the shear and clamping force, so the quality and performance of the extended wheel bolts are especially important.

If you buy 15mm 2023 Audi A4 wheel spacers from BONOSS, you can get more discounts with longer wheel bolts, and the system will automatically match the corresponding lengths without having to check the length of the stock wheel bolts. 12.9 grade extended wheel bolts are made of SCM440 steel alloy. They can provide a minimum tensile strength of more than 1282 MPa and a proof load of 121,000 N. There is no need to worry about reduced performance with longer wheel bolts. 12.9 grade wheel bolts are suitable for trucks with higher load capacity, which is sufficient for cars.

Although the 15mm 2023 Audi A4 wheel spacers are not the subject of force, BONOSS insists on using high-performance 6061-T6 and 7075-T6 forged aluminum alloys as raw materials. The forged aluminum alloys have excellent toughness and significantly higher ultimate tensile strength, and the dense internal metal structure reduces the risk of air pockets or structural fractures. In addition, 7075-T6, a higher variant material, differs from most wheel spacers manufacturers. It can provide 572MPa ultimate tensile strength, 40% higher than 6061-T6 in performance.

Do You Need Longer Wheel Bolts for 15mm 2023 Audi A4 Wheel Spacers?

Some customers thought the stock wheel bolts could still be used on the 15mm 2023 Audi A4 wheel spacers for fixing. This would cause the wheel to fall off or shake. The Audi A4 stock wheel bolts are 27mm long, and the 15mm 2023 Audi A4 wheel spacers would require 27+15=42mm extended wheel bolts. The threaded engagements will ensure that all parts are secured.

Some customers may choose smaller wheel spacers, 5mm or 8mm 2023 Audi A4 wheel spacers. They still require longer wheel bolts. Using stock wheel bolts may cause excessive shear force on the bolt section under leverage and risk of breakage. Whether it is 5mm or 15mm 2023 Audi A4 wheel spacers, they must use longer wheel bolts.

How do the 15mm 2023 Audi A4 Wheel Spacers Stay Centered?

The secret to keeping the 15mm 2023 Audi A4 wheel spacers in the central position is that BONOSS uses CNC machines to machine wheel spacers with 0.02mm accuracy. Most wheel spacers manufacturers produce 0.2mm accuracy universal or lug-centric wheel spacers, which can be used across the hub assembly. However, the hub assembly, like the inside of the wheels, has a nested structure that will create enough static friction to help hold them in place. Universal or lug-centric wheel spacers do not have a raised center hole nested structure, resulting in wheel spacers being held in place by wheel bolts.

The wheel bolt fixing is subjected to the clamping force of wheel fixing and the uneven feedback from the road, which leads to the variation of the diameter of the bolt hole pitch. The variation of the bolt-hole seat or pitch diameter will reduce the bolt clamping force of the bolt, which will affect the fixing of the wheel. BONOSS recommends using 15mm 2023 Audi A4 wheel spacers with hub-centric construction, which will reduce the problem of spare parts.

Since the 15mm 2023 Audi A4 wheel spacers are of slip-on construction, it is the easiest way to check the fit by clamping a piece of paper between the parts after sliding the wheel spacers into the hub assembly. Turn the 15mm 2023 Audi A4 wheel spacers to see if there is any jamming. Using abrasive paper and rust remover will reduce the debris and rusty parts of the hub assembly.

BONOSS’ 15mm 2023 Audi A4 wheel spacers are machined to a precision of 0.02mm, which not only requires the hub-centric and lug pattern of the wheel spacers to be very precise but also requires the hub assembly to have no impurities. 15mm 2023 Audi A4 wheel spacers’ hub centric will perfectly match the inner side of the hub assembly and the wheels.

Will 15mm 2023 Audi A4 Wheel Spacers Damage Wheel Bearing?

Wheel spacers have a close relationship with wheel bearings as wheel spacers increase the wheel clearance and the length of the wheel track, which in turn helps the vehicle to get a more stable force structure, the increase of stability will increase the force of mechanical parts to some extent. There is a reason why modern car manufacturers use aluminum alloy to make car chassis, it is lightweight and has good toughness. Similarly, it is feasible to choose forged aluminum 15mm 2023 Audi A4 wheel spacers.

If you install 50mm wheel spacers on a normal sedan, wheel spacers made of any material will have a greater impact on the wheel bearing. BONOSS has made a more hollow design based on the previous generation’s 15mm 2023 Audi A4 wheel spacers. Each lightweight wheel spacer is about 30% less weight than the previous generation. The lightweight design is more suitable for sedans like the 2023 Audi A4.

The lightweight design does not affect the structural strength of the 15mm 2023 Audi A4 wheel spacers, which will be related to whether the above-mentioned wheel spacers are subjected to forces or not. More force will be applied to the wheel bolts, and 15mm 2023 Audi A4 wheel spacers can be considered an extension of the hub assembly mounting surface. If you are still concerned about the wheel spacers, choosing 7075-T6 forged aluminum alloy 15mm 2023 Audi A4 wheel spacers is safer. Meanwhile, BONOSS provides up to 10 years of quality warranty.
