These items are made of exactly Alfa Romeo spacers specifications: Bolt Pattern (PCD): 5×110, Center Bore (CB): 65.1, Thread: M12x1.25. As long as the vehicles share the same bolt pattern, center bore diameter, and thread size with Alfa Romeo 940 Giulietta, these items can also be used as wheel spacers for those vehicles. What are the benefits of installing BONOSS wheel spacers on Alfa Romeo? Wheel spacers provide many benefits to your Alfa Romeo. For example, clearing suspension clearance issues after mounting bigger wheels and tires, better steering experience and more grip power, better ability to roll over obstacles. In addition, pushing your wheels out to a certain distance allows you to add a bigger brake kit without rubbing the wheel. BONOSS wheel spacers provide all the benefits above.

In addition, BONOSS spacers apply Global Pioneer Active Cooling Technique which utilize the rotation of the spacers to allow the external cold air entering and continuously flowing inside the spacers, enhancing the heat dissipation of the braking system, reducing brake fade. The braking efficiency gets improvement, driving is safer.

How does the active cooling function works on my Alfa Romeo? The special petal shape grooves utilize the rotation of the spacers to allow the external cold air entering and continuously flowing inside the spacers, enhancing the heat dissipation of the braking system. Installing BONOSS active cooling wheel spacers helps improve the heat dissipation of the brake system, reducing brake fade while providing the functions of traditional spacers.

The cost of manufacturing an active cooling wheel spacer is nearly equal to the traditional alternative. Are Alfa Romeo wheel spacers safe? Wheel spacers are used to widen the track of cars, also widely used to fix backspacing and clearance issues. Quality is important to ensure safety. BONOSS wheel spacers are designed with actual measurement, using forged 6061-T6 aluminum alloy material (tensile strength = 310Mpa), and matching with ISO standard grade 12.9 wheel bolts and ISO standard grade 10 lug nuts, which are over 66 SGS TÜV test reports certificated.

Precision at 0.02mm tolerance, which offers high surface quality, more importantly, safer and more professional. Why your Alfa Romeo need hubcentric wheel spacers? Hub centric wheel spacers pilot by the center bore of the vehicle hub. This means they center on the hub of the vehicle while simulating the piloting lip on the face side. Besides, according to the size of the hub centric lip, they transform lug centric wheels into hub centric wheels.

Most vehicles need hub centric wheel spacers to create a strong hub-spacer-wheel connection. Based on traditional hubcentric 940 Giulietta spacers, BONOSS has optimized this design for further reducing the chance of high-speed vibration, it is called multi-stage hubcentric design. According to the actual test, the effect of BONOSS multi-stage hubcentric wheel spacers is far better than the common alternatives, which fit more perfectly, safer and more stable. What are these Alfa Romeo wheel spacers made of?

BONOSS manufactures 940 Giulietta wheel spacers with aircraft-grade forged 6061-T6 billet aluminum alloy, which features many desirable properties such as high strength, wear-resistance, excellent toughness, impact resistance and high-temperature resistance. This metal performs good mechanical properties: Tensile strength=310Mpa, Yield strength=275Mpa and Failure Elongation~10%. In fact, they are cheap casting spacers. Forging provides higher performance spacers than casting. It further enhances the hardness and toughness of the spacers. With the same material and cost, the strength and safety of forged spacers are far higher than casting ones. What's the performance of the matching wheel bolts of wheel spacers? What does the "BONOSS Engraved" means? The matching wheel bolts of BONOSS spacers applied high-strength JIS SCM440 steel material. They have achieved ISO standard grade 12.9, tensile strength=1,220Mpa, limited life range test=2,000,000 stress cycles without damage, ultimate tensile load=152,000N, hardness (HV)=395, NSS=500H. And the matching inset lug nuts have achieved ISO standard grade 10, proof load=1110Mpa, hardness (HV)=349, NSS=500H.

Many competitors often use other brands of bolts and nuts in pursuit of lowering the cost, and these bolts and lug nuts are often only marked with metric units without brand engraved. In view of this, each BONOSS matching wheel stud as well as lug nut is "BONOSS engraved", meaning these matching wheel bolts are made by BONOSS's own factory, the quality is guaranteed, customers' interests are protected, and BONOSS takes the quality responsibility.
