Can 2022 BMW 3 Series G21 wheel spacers help to install aftermarket brakes and other accessories? Should I use the slip-on or bolt-on 2022 BMW 3 Series G21 wheel spacers, and what size will 2022 BMW 3 Series G21 wheel spacers fit G21?
If you want answers to the questions above, read our content below for help. The G21 is classified under the G20 as a Touring version. However, we still want to cover the Touring version separately because the excellent driving experience makes you forget about the wagon’s bulk. 330i’s smooth, low-roar engine draws the line at lack of power, the xDrive system provides extra traction, and turning on sport mode will give the rear wheels a burst of torque with more oomph.
Will 2022 BMW 3 Series Wheel Spacers Help with Aftermarket Brakes?
The BMW 3 Series G21 tuning program is necessary for braking system upgrades. When you have a BMW 3 Series with excellent handling, you first want to compete on track days, and the braking system is essential as a safety safeguard. Stock brakes are indeed good, but aftermarket brakes, such as Endless, AP Racing, Alcon, etc., can give you the feel of handling that is more suited to track driving. Most customers choose aftermarket brakes focusing on brand and product features but tend to overlook the size of the aftermarket brakes, which leads to the installation of aftermarket brakes rubbing against the wheel spokes or failing to fit.
Honestly, it is not worth giving up BMW wheels or aftermarket brakes for the extra 10mm-15mm of fitting space. 2022 BMW 3 Series G21 wheel spacers can solve the fitting problem of aftermarket brakes and wheels.
2022 BMW 3 Series G21 wheel spacers are used to increase the clearance and adjust the stock wheel offset. The reason that aftermarket brakes cannot be mounted in the stock wheel offset is large, and the distance between the wheel mounting plane and the level of the wheel spokes is short because aftermarket brakes are wider than the stock part. 2022 BMW 3 Series G21 wheel spacers increased clearance provides room for mounting, allowing aftermarket brakes to be mounted on the vehicle.
The 2022 BMW 3 Series G21 stock wheel offset is between 25-30. For example, with 15mm 2022 BMW 3 Series G21 wheel spacers, the offset becomes 10-15, a smaller offset value means the wheel is positioned more outwards.
Which Type of 2022 BMW 3 Series G21 Wheel Spacers Should I Use？ Slip-on or Bolt-on？
Slip-on 2022 BMW 3 Series G21 wheel spacers refer to the fixing with lug bolts, usually the thickness of slip-on wheel spacers under 20mm; extended lug bolts need to apply sufficient clamping force and accept the shear force from vehicle acceleration, using slip-on wheel spacers requires you to spend more time to find high-strength lug bolts for fixing. Bolt-on wheel spacers will provide lug bolts to fix the hub assembly, and using stock lug bolts to fix your wheels, 20mm or more thickness, will offer more possibilities. Both types of 2022 BMW 3 Series G21 wheel spacers are safe as long as they are hub-centric. Otherwise, shaking and vibration will happen to your vehicle.
If you need to solve the fitment problem of aftermarket brakes and wheels, we recommend the slip-on 2022 BMW 3 Series G21 wheel spacers. The 20mm thickness can provide enough space for aftermarket brakes. Another reason is that some customers are concerned about weight and geometry issues.
BONOSS’ slip-on 2022 BMW 3 Series G21 wheel spacers are all part of the Lightweight Plus series, which has a more hollow design and an average weight reduction of 30% by optimizing and upgrading the previous generation. In addition, the smaller thickness has a much smaller impact on the front wheel scrub radius, and its effect can be ignored with the help of modern electronic power assist systems.
You don’t need to search for high-strength lug bolts to match 2022 BMW 3 Series G21 wheel spacers. When you choose BONOSS Lightweight Plus wheel spacers, our system automatically provides the proper length lug bolts based on the thickness of the wheel spacers. Check the matching lug bolts when purchasing 2022 BMW 3 Series G21 wheel spacers. BONOSS 12.9 grade lug bolts are not just parts to hold the wheel in place; we have added many details to the lug bolts, including a 12-piece pattern on the head that uses super forging one-time forming craftsmanship.
Forging one-time forming craftsmanship, which cannot be presented in a later turning process. The seat of the lug bolts adopts a spacer structure, effectively eliminating the bolt’s loosening and the abnormal sound caused by the PCD hole coaxially deviation between the hub and hub assembly while driving. BONOSS has engraved logos on the head and bottom of the lug bolts to reflect that it is a BONOSS product.
Are 2022 BMW 3 Series G21 Wheel Spacers Safe?
As mentioned above, the 2022 BMW 3 Series G21 wheel spacers are mounted between the wheel and hub assembly, and the lug bolts are fixed through the slip-on wheel spacers and the wheel. Although BONOSS provides lug bolts in the corresponding lengths, you should be informed that if you purchase lug bolts by yourself, you must pay attention to the bolt pattern.
The 2022 BMW 3 Series G21 wheel spacers need to be matched with M14x1.25 tapered lug bolts, and the length should be calculated according to the length of the stock lug bolts and the thickness of the 2022 BMW 3 Series G21 wheel spacers installed. For example, if you install 20mm 2022 BMW 3 Series G21 wheel spacers, you will need 27+20=47mm lug bolts. The extended lug bolts have more threads to allow engagement to a safe number of turns, creating a clamping force to hold the wheel in place.
2022 BMW 3 Series G21 wheel spacers were installed to increase the length of the track and the length by 2x because, usually, wheel spacers need to be installed on the left and right side to keep better balance. For example, 10mm 2022 BMW 3 Series G21 wheel spacers will increase the track by 20mm, which is acceptable for the 2022 BMW 3 Series G21. The 2022 BMW 3 Series G21 adds more aluminum alloy elements to the suspension and drivetrain, reducing the body’s weight.
Similarly, the 2022 BMW 3 Series G21 wheel spacers are also made of aluminum alloy, so you don’t have to worry about the weight of these two 2022 BMW 3 Series G21 wheel spacers. Geometrically, the scrub radius adjustment is only present at the front wheels. The increased grip at the front wheels ultimately reduces the tendency to understeer, allowing the car to go through corners at higher speeds. This feeling will be influenced by the thickness of the 2022 BMW 3 Series G21 wheel spacers, and the driver may feel sharper feedback from the vehicle when driving on the track.
The hub-centric design makes the 2022 BMW 3 Series G21 wheel spacers safe, and the wheel spacers’ hub-centric protrusions are shaped according to the wheel’s recessed hub-centric to ensure greater accuracy. The inner side of the wheel spacers uses a professional measuring tool to measure the neck diameter and other data. Hub-centric wheel spacers have the precision that lug-centric wheel spacers lack, better centering the wheel and helping to distribute the vehicle’s weight more evenly.
Aluminum 2022 BMW 3 Series G21 wheel spacers are more balanced than steel alloy products and products made of other materials. In addition to the obvious weight advantage, the forged aluminum alloy material enhances tensile strength and yield strength. Forging 7075-T6 aluminum alloy tensile strength reached 510-572MPa, and yield strength came 434-503MPa. BONOSS keeps testing our products through the third-party testing agencies SGS and TUV to obtain a more convincing test report. You can find these test results on the official website of BONOSS.
