The BMW E39 74.1 to 72.5 wheel adapters can not only give you the proper spacing but also convert the center bore to adapt a variety of aftermarket wheels. They are capable to transform lug-centric wheels into hub-centric ones. The hub side of the spacer is machined to fit the OEM vehicle hub and the other side is made to a different center bore size to fit aftermarket rims. For example, if you want to convert a 74.1mm center bore to 72.5mm, BMW E39 74.1 to 72.5 wheel adapters will be the solution.
Technically speaking, you can run 10mm to 30mm BMW E39 74.1 to 72.5 wheel adapters with no problems. However, the fender gap determines how thick the wheel adapters will fit perfectly. Take a straight edge and place it against the outermost part of the rims/tires, then measure from the outside wheel to the fender line to see how much space you have available. Repeat this on the front and rear wheels. For instance, if the value is 15mm, then it is recommended to use 15mm BMW E39 74.1 to 72.5 wheel adapters.
Who Makes Good BMW E39 74.1 to 72.5 Wheel Adapters?
For wheel connection components, the higher the precision, the better the BMW E39 74.1 to 72.5 wheel adapters will fit, thus, the safer your driving will be. The precision of BONOSS BMW E39 74.1 to 72.5 wheel adapters has reached 0.02mm. Precise hub-centric M5 conversion spacers provide high surface integrity, effectively guarantee safety, stability, and reliability, and ensure the smooth operation of vehicle wheel parts. In order to further optimize the hub-centric connection, BONOSS 5 Series BMW E39 74.1 to 72.5 wheel adapters are designed with better multi-stage hub-centric lips.
BONOSS makes adjustments to the hub-centric BMW E39 74.1 to 72.5 wheel adapters according to the actual vehicle hub design. In this case, some hub-centric wheel spacers are machined with a chamfer on the interface of the hub-centric lip. BONOSS hub-centric BMW E39 74.1 to 72.5 wheel adapters are designed with better multi-stage hub-centric lips. The hub-centric ring is machined to be multi-layers, and the bevels fit the corresponding hub flange, which eliminates any possible gaps. Thus, precise hub-centric BMW E39 74.1 to 72.5 wheel adapters will not cause any kind of vibrations.
Do BMW E39 74.1 to 72.5 Wheel Adapters Affect Acceleration?
On average, BONOSS 20mm BMW E39 74.1 to 72.5 wheel adapters weigh only about 1 lb (447g) each. Adding such a small lightweight component wouldn’t noticeably slow a car down. In other words, they will not affect the acceleration significantly. These BONOSS BMW E39 74.1 to 72.5 wheel adapters are precisely cut with some “hollow holes”. Due to these hollow holes, the average weight of each spacer is more than 30% lighter than the previous-gen product. Such BONOSS BMW E39 74.1 to 72.5 wheel adapters are perfect for performance improvement and appealing look enhancement.
In addition, BONOSS BMW E39 74.1 to 72.5 wheel adapters are made of forged aluminum alloy. Lighter-weight aluminum allows them to operate well at a higher performance in most conditions. What’s better, they have good thermal conductivity which makes them dissipate brake heat better. The forging process allows the M5 conversion spacers to have a very high weight-to-strength ratio. As a result, BONOSS forged lightweight plus BMW E39 74.1 to 72.5 wheel adapters are much strong with much less weight.
