Project Description

Performance upgrade! Several days ago, this Audi RS5 installed BONOSS Forged Lightweight Plus Wheel Spacers, front 15mm (3/5 inch), PCD 5×112, CB 66.5 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. Wheel spacers create an additional clearance between your wheel and the vehicle hub. An ideal distance between your car’s wheels quite actually makes it more stable. They also increase the traction during cornering and can allow you to add larger wheels. And the hub centric is designed specially to suit the Audi OEM axle hub, meaning no vibrations, fewer stress loads and more service life range. (Thanks IG PERFORMANCE for providing these pics)


There is no other car that provides a fast, fun, luxurious, and elegant drive like the Audi RS5. It is a peak of high performance and practicality. The RS5 gets a gorgeous appearance, advanced technology, and lavish features. It has a charming powertrain, a mighty 444-hp 2.9-liter twin-turbo V-6 engine, providing 443 lb-ft of torque, an eight-speed automatic transmission, offering smooth, sharp switch, the Quattro all-wheel-drive system help deliver fast acceleration and dynamic responses.

BONOSS Forged Lightweight Plus Wheel Spacers Dismounting Grooves Design

Effective Dismounting Grooves Design

Dismounting grooves means the small notches which are distributed on the corner of wheel spacers. It is designed to easily dismount the spacers, improving the user experience. Normally, it leaves a limited clearance between the axle plate and spacer, using a screwdriver can easily remove the spacers, simple and efficient. If there is no such groove, the spacer will snug the vehicle hub, by forces effect, it can be difficult to dismount. Even worse, you may destroy the spacers or axle hub. Furthermore, the grooves can reduce the weight of spacers, which is good for increasing the effect of lightweight design.

Important Concerns for Lug Bolts Installation

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