Rogue Engineering Wheel Spacers

(Enlarge image of 12mm and 20mm spacers for detailed images of a chamfered wheel hub)

Rogue Engineering wheel spacers start from 100% billet 6061-T6 aluminum round (not cut from plate). From there, they are machined entirely on CNC lathes and mills to ensure absolute roundness and thickness. Production runs are tested at random to ensure absolute balance, trueness and dimension.

Rogue Engineering's new "window" design removes the maximum amount of weight possible from the spacer itself. For example, their new 10mm spacer design is 40% than a common German brand. With so much focus on lightweight wheels, installing a wheel spacer in excess of 1 pound seems like a neglected oversight. Now, with RE's new design, you can have your spacer while adding minimal weight to the wheel assembly area.

Unique Features:

• Chamfered back face means the end to spacers stuck on your wheels
• Thickness engraved on the front of each spacer to eliminate guesswork
• M12 wheel lugs INCLUDED - these required bolts are an additional purchase with other brands (X5 requires 14mm lugs, not included)

The following spacer widths are a available:

• 10mm
• 10mm Flat* (2 piece spacer) [does not have window design]
• 12mm
• 15mm
• 18mm [does not have window design]

All spacers fit BMW 5x120 bolt patterns with 72.5mm hub flanges (not E39, E70). We do not produce any 4x100 patterns (older 3-series BMWs).

* 10mm flat spacers are for use on the FRONT hubs only and are not compatible with E39, E46 Xi, E92 or E30 M3.

These spacers fit 5 lug BMWs (note E39 specific spacer). 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 pictures linked below to determine correct use.

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.

Wheel spacers ARE NOT RETURNABLE if plastic packaging is opened.
