Rogue Engineering Wheel Spacers start from a 100% billet 6061-T6 aluminum round (not cut from plate). They're then machined entirely on CNC lathes and mills to ensure absolute roundness and thickness. Rogue Engineering tests production runs at random to ensure absolute balance, trueness, and proper dimensions.  Our spacer is the original lightweight spacer!  Why buy $9000 lightweight wheels only to put boat anchor spacers on?

Features of the Rogue Engineering wheel spacers include:

  • Unique chamfered back face means the end to spacers stuck on your wheels
  • Thickness engraved on the front of each spacer to eliminate guesswork
  • "Window" design removed the most weight!  Our 10mm spacer is 40% lighter than a common German brand!
  • BLACK Wheel bolts are included (except for 18mm M14 bolts)
  • BLACK anodized finish
  • Made in the USA

    All RE spacers fit BMW 5x120 bolt patterns with 72.5mm hub flanges (not E39, E70). 4x100 patterns for older 3-Series BMWs are not available.

    These spacers fit 5 lug BMWs (note E39 specific spacer above). Each set includes 2 spacers (one axle set) and 10 lug bolts. Your wheels may or may not allow the use of 10 and 12mm spacers - please refer to images to determine correct use.

    Wheel spacers ARE NOT RETURNABLE if plastic packaging is opened.

    Special Notes about 10mm/12mm spacers
    Note that the hub contour height for use with our 10mm/12mm spacers requires a maximum dimension of 11.5mm. Anything taller (such as rust buildup or dust caps) can damage the spacer or even break off the hubcentric lip machined onto the spacer. Please measure your hub to ensure compatibility before ordering. Spacers that are damaged because of excessive hub contour height are not covered by Rogue Engineering's warranty policy.

    10mm and 12mm spacers require rims with chamfered hub faces. Enlarge image of spacers for detailed images of a chamfered wheel hub. Wheels found to be incompatible with these 10mm/12mm spacers, because of an insufficient rear chamfer depth, include some Kosei K1 models.

    Installation Information
    The hub surface upon which the wheel spacer will be mounted should be adequately prepared before installation. This means all surface corrosion should be cleaned with a wire brush or steel wool to ensure a clean surface. A thin film of grease or anti-seize compound on the face of the wheel hub will aid in the future removal of the spacer. The spacer should slide over the hub without being forced. Using a hammer, mallet or other "tools of persuasion" on the wheel spacer for installation is not recommended and immediately voids any product warranty.

    Wheel Bolt Information
    All Rogue Engineering wheel spacers now include BLACK wheel bolts that are ISO/TS 16949 and ISO 9001 by TÜV. The finish is very close to BMW's OEM finish which is both corrosion resistant and durable. 
    Regardless of color of the bolts, wheel bolts should be considered consumable items.That's right, they do not last forever. If you never remove your wheels, this is a different story. However, if you remove and change wheels often (winter tires, track wheels, etc.), consider changing your hardware at least on a yearly basis to prevent premature hardware failure.

    How Tight is Right?
    It is important to note lug bolt torque. Fnd the picture above of a lug bolt torqued to 90 ft. lbs. (according to the customer) using grease on the threads. BMWs current specification on M12 wheel bolts is 88 ft. lbs. (higher for M14 bolts). This specification is with dry threads. Anti-seize, grease, or other lubricants on the threads of the bolt can, and will, artificially lubricate the threads, causing an inaccurate torque reading when using a torque wrench. This can yield a situation where the bolt is actually over-torqued (as shown in the case below).

    What Length Wheel Bolts?
    Some aftermarket wheels may have THICKER than OEM wheel pad widths (for strength, added rigidity, or simply because of the design), and require longer than stock wheel bolts for adequate thread engagement. Because of the multitude of aftermarket wheels, we cannot provide technical data as to how long your bolts need to be to fit non-OEM wheels. Additionally, the bolts we provide with the spacers are designed to replace factory bolts on factory wheels. We do not offer mixing-matching of bolts with spacers to accommodate non-OEM wheel pad dimensions. 

    BORING FINE PRINT.  IF YOU BUY THE OUR SPACERS, YOU AGREE TO THE INFORMATION BELOW:
    Wheel bolts used with spacers installed and removed frequently should be considered consumables (like brake pads and brake discs) and should be replaced on a regular basis, based on use. Wheel bolts supplied means that you accept liability for measuring and ensuring that there are enough threads engaged for your wheel application, as all wheels can vary. Repeated installation and removal can cause wheel bolts to stretch and ultimately break. Torque on bolts should be checked on a regular basis. Replacement wheel bolts are available for purchase. We recommend checking bolt torque after the first 50-100 miles initially and regular intervals afterwards. Failure to do so may cause the wheel bolts to loosen and/or fail. Follow factory recommended wheel bolt torque.
