After installing BONOSS Audi S5 Shell-type Wheel Bolts, this vehicle becomes more excellent and personalized! Most aftermarket wheels (e.g., HRE Wheels, RAYS Wheels, BBS Wheels) are manufactured to fit a wider range of vehicles without having a specific specification. Due to the difference in the lug seat type of the wheels, the Audi stock wheel bolts may not fit the new aftermarket wheel rims. The wheel bolts are relatively small components under extremely large forces, and they are absolutely critical to locking the wheel on your vehicle so that the correct seat type and other fitment are quite important. Aesthetically, by installing new style bolts, you can make your Audi S5 look personalized and different.
