Project Description

Performance upgrade! Last Monday, this Audi Q3 F3 installed BONOSS Forged Lightweight Plus Wheel Spacers, front 15mm (3/5 inch), rear 20mm (4/5 inch), PCD 5×112, CB 57.1 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. What do wheel spacers do? By pushing out the wheel, you can gain a small amount of clearance for mounting larger brake calipers without wheel scratching. Larger brake calipers bring better braking performance. Wheel spacers offer a cost-effective and efficient solution for your brake system modifications. These spacers and bolts are specifically engineered to give your car better cornering, aerodynamics, and look. (Thanks CHEGUANJIA for  providing these pics)


The Audi Q3 F3 is one of the most popular mid-size SUVs in the world, complete with an avant-garde design, premium interior, comfortable seats, and stylish cabin. The new Q3 is powered by a turbocharged four-cylinder engine, delivering 228 hp at 5000 rpm, 258 lb-ft torque at 1700 rpm, an eight-speed automatic transmission, offering smooth, sharp switch and it is Quattro all-wheel drive. The best bit with this Q3 F3 is the driving experience, and Audi was always not to disappoint here. The steering is precise and direct, body control is excellent and the handling is anything but enjoyable.

BONOSS Forged Lightweight Plus Wheel Spacers

What are wheel spacers?

Wheel spacers are a kind of wheel accessories which are used to create necessary distance on the inner portion of the wheel for clearance problem with brakes, tie rods and other suspension components. That means they allow for installing bigger wheels and tires as well as larger brake calipers without breaking the fender. When your wheels do not have enough offset. A wheel spacer will compensate for proper offset by pushing the wheel farther away from the vehicle hub. Besides, hub-centric wheel spacers can transform a lug-centric wheel (one that centers by fastening the wheel lugs rather than a hub-specific mounting surface) into a hub-centric wheel.

Why do extended wheel bolts do?

Extended wheel bolts (also called longer wheel bolts, extended lug bolts) are designed with longer thread lengths to allow full thread penetration with wheel spacers or wider aftermarket rims of a different offset. Any time you run wheel spacers, extended wheel bolts are a must option to properly secure the wheel to the vehicle hub. Without the proper thread length, the stock lug bolts will not allow penetrating the vehicle hub threads completely which can cause car shaking or safety risk. BONOSS Forged Grade 12.9 Extended Wheel Bolts are all thoroughly tested and certified by SGS, TUV authoritative institutions, truly guarantee safety.
