“Making no mistakes, these shell-type red bolts perfectly match the red calipers”, said the owner: “Love my car more than ever now!” Indeed, the color of the bolts helps embellish the style of your car, hence you can choose a set of aftermarket lug bolts for your Audi S4. Although Audi manufacturer tries to make its own car unique in style, in order to cater to the public’s aesthetics and acceptance, the OEM wheels are generally designed to be more universal. For many Audi S4 owners who pursue personality and beauty, it is not enough to satisfy their daily use, so the idea of changing the wheel style is growing popular. As a crucial part of locking the wheel rims, the lug bolts are actually an instant beginning of wheel style changing.

Are these shell-type wheel bolts the same as the common bolts? Exactly BONOSS has upgraded the exterior of traditional lug bolts, matching the bolt with a shell for protecting the bolts from debris and water corrosion and maximally beautifying your wheels. The main part of the bolt is made of high-strength SCM440 alloy steel, after the forging process by BONOSS factory, they have fully passed ISO Grade 12.9 performance test. The shells of the bolts are able to change, in BONOSS stock, we have eight colors to meet your needs. Changing to new lug bolts is not expensive, but it is the fastest part of enhancing the visual effect. At the same time, if you use lighter wheel bolts, they will improve the performance of the vehicle to a certain extent. (Thanks to the ower for supporting.)

How to Install Audi S4 Wheel Bolts Safely?

The wheel bolts need to be installed correctly, and they also must be properly torqued to manufacturer-recommended torque specs. This means making sure the lug bolts, wheel, and hub are secured enough to where they don’t get loosen. Untightened lug bolts (the clamping force is not enough) or overtightened lug bolts (the wheel bolt has been stretched past its tensile strength limit, so the clamping force has gone away) will cause most lug bolts failures. Find a suitable balance in the level of tightness and the stud will remain strong, providing the greatest possible force to lock the wheel to the hub. This ensures the wheel bolts safe.

We know these wheels are very valuable for you. This is why we have designed these lock bolts with an irregular outer diameter shape head which requires a special key tool to loosen and remove. They come with an anti-theft function for protecting your finest wheels. Even if the thieves have a full set of socket wrenches, they won’t have the unique shape socket to fit. This effectively decreases the stolen risk of your wheels. The only time the wheel lug bolts can be removed is when the key socket with the correct pattern is inserted. Besides, various colors are available for your preference.
