BBS Technology

Manufacturing Detail
Air Inside Technology:
A dynamic driving experience that isn't heavy on the road - thanks to our Air Inside Technology, our light alloy wheels come very close to delivering exactly that. The hollow-chamber construction of the wheels, which is inspired directly by nature, markedly reduces the volume of the rotating masses while markedly increasing the wheels' stability and load-bearing capacity. Air Inside Technology involves introducing hollow chambers into our light alloy wheels in different places depending on the wheel type, e.g. in the centre or in the inner or outer shoulder. This significantly reduces the weight - even by several kilogrammes per wheel in some cases. At the same time, resistance to deformation of the flange increases by up to 60%.
Rim Protector:
With our patented rim protector made of polished stainless steel, you can permanently safeguard the high-quality look of your wheels. Should damage occur, the rim protector is now available as a replaceable spare part and can be exchanged quickly and easily without having to replace the entire rim or remove the tyre.
Rim Shoulders:
Under normal driving conditions, the rim shoulders are put under a lot of pressure and it is their job to protect the tyre bed and, together with the hump, ensure that the tyre remains in place. To guarantee optimum stability, a higher strength material is used for this section of the light alloy wheel. However, this increases the weight and the rotating mass and makes the wheel more difficult to steer. By applying Air Inside Technology to all of its wheel types, BBS is able to counteract these effects by using hollow rim shoulders to combine weight optimisation with outstanding stability.
Milled Spokes:
Milling the spokes allows BBS to hit just the right balance between wheel weight and stability. Using a special CNC milling process, the parts of the wheel that do not contribute to its stability can be removed. Before a prototype is checked for durability at our test facility, a computer simulation of the wheel type is subjected to several test cycles using different spoke configurations to already ensure the correct balance is achieved during the construction phase.
Undercut:
During the undercut phase, all of the areas on the inside of the centre of the rim that can optimise weight reduction are processed using special lathe and milling tools so that all excess material can be removed and the wheel's rotating mass can be decreased. During this process, special attention is given to the optimisation of the inside of the spoke and the bolt circle. Implementing this technology enables us to use less material to produce more complex shapes with increased stability.
Hollow Moulding:
This technology involves hollow moulding the wheel rim's inner and outer shoulders and the spokes using the flow forming method. The aluminium lips that are prepared at the casting stage are moulded into a hollow shape during flow forming using special tools on a rotating cylinder before being laser-welded together. This complex process results in up to 60% more resilience against deformation as well as reductions in weight, due to the hollow chamber construction, and wheel inertia.
Ceramic Polishing:
This technique is the most innovative and highest form of surface finishing. When ceramic polishing, a special aluminium alloy is used for the wheels and high-strength ceramic particles are used in the pace of normal polishing particles such as stainless steel ones. The advantage: due to their smaller size and increased strength, the ceramic polishing particles result in closer polish than achieved using normal polishing particles. The result: an ultra smooth surface and a chrome-like appearance without bringing with it the disadvantages associated with an actual chrome surface such as additional weight or brittle material. Ceramic polishing technology is currently only used as original equipment for the most famous manufacturers but will soon be available as a customisable option for exclusive wheel types and vehicles.
Ball Polishing:
Ball polishing is more than just a surface finish as it considerably strengthens the wheel's surface. During this process, the light alloy wheels are placed in a large, vibrating rotation cylinder. Inside the cylinder the wheels are polished with millions of tiny stainless steel ball bearings. This not only strengthens and hardens the wheels, it also leaves them with an unbeatable shine.
Multi-Piece Wheels:
When light alloy wheels are produced using more than one component they are called multi-piece light alloy wheels. Two-piece BBS light alloy wheels consist of the rim and the wheel centre, three-piece light alloy wheels consist of two rim halves and the wheel centre. The individual components are firmly attached to each other using titanium bolts. If one of the components becomes damaged, it can be detached and replaced separately by an expert at little expense.
Monobloc Technology:
BBS monobloc light alloy wheels combine the lightweight construction of the special BBS alloys with the highest level of stability. To guarantee this, all monobloc wheel types are cast in one piece and are subject to rigorous checks at the end of each production stage to ensure stability. Monobloc wheels also offer a further advantage: their sports characteristics which are the result of unique alloys coupled with the lightweight construction.
Nano Paintwork:
Nano paintwork was developed using innovative nano technology and is a special coating that protects against dirt and dust. This type of paintwork considerably enhances the surface's soil-resisting characteristics so that it can repel water and dirt without any chemical assistance. The result: oily liquids, dirt and brake shoe residue hardly ever stick to the wheel's surface and if they do, they can be wiped away incredibly easily. Nano paintwork is also scratch and heat resistant as well as incredibly tough.
Strength-To-Weight Ratio:
When constructing new light alloy wheels, particular attention is always given to one thing: achieving the perfect balance between weight and stability which is known as the strength-to-weight ratio. In general, the more stability offered by a tyre means the heavier it will be. However, the fact that there are exceptions to every rule is proven by innovative BBS developments. For example, the spoke's hollow chamber, the inner and outer shoulder, spoke milling and weight-optimised rim centres couple maximum stability with a minimum rotating mass. The result: considerably better handling and increased performance.
