Project Description

Perfect fit! Last Sunday, this BMW M4 Competition F82 installed BONOSS Forged Lightweight Plus Wheel Spacers, front 12mm (1/2 inch), rear 15mm (3/5 inch), PCD 5×120, CB 72.5 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. Why do wheel spacers do? By pushing out the wheel, you can gain a small amount of clearance for bigger wheels instead of rubbing against the fender. Having your wheel brought out ideal distance allows for mounting larger brake calipers without wheel scratching. These spacers and bolts are specifically engineered to give your car better cornering, aerodynamics, and look. They match perfectly with the vehicle hub, due to the 0.02mm tolerance precise process.

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. By pushing out the wheel, you can gain a small amount of clearance for bigger wheels instead of rubbing against the fender. Having your wheel brought out ideal distance allows for mounting larger brake calipers without wheel scratching. Furthermore, hub-centric wheel spacers can transform a lug-centric wheel (one that centers by tightening the wheel lugs rather than a hub-specific mounting surface) into a hub-centric wheel.

BONOSS Forged Grade12.9 Extended Wheel Bolts

Why do you need extended wheel bolts?

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.

Addtional Information:

  • BONOSS wheel spacer thickness can be customized flexibly, which is compatible with most vehicles. Thus, if you would like different sizes of wheel spacers, feel free to contact us. This BMW M4 Competition F82 uses front 12mm (1/2 inch), rear 15mm (3/5 inch), PCD 5×120, CB 72.5.
  • The extended bolts are spacer structure design, which effectively eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxially deviation between hub and shaft head. This BMW M4 Competition F82 uses conical seat bolts. If you would like a set of extended bolts, please ensure the seat type of the bolts is suitable for threading tightly. And, if you don’t know the proper length, you are welcomed to contact our tech staff freely.
