Construction and Material
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. If we haven't stated the obvious, these are produced exclusively for us in the USA.
Unique Features
Being longtime wheel spacer users, we've been frustrated with common spacer issues. By addressing some of these minor issues, we are able to make a more functional wheel spacer.
One issue is the dreaded "stuck" spacer. There is the occasion, that a spacer may become "stuck" to the brake rotor surface, making removal very difficult or near impossible. Because all wheel spacers that are produced have virtually flat back surfaces, you cannot wedge anything to pry off the spacer. Not even the thinnest screwdriver or chisel will fit. Rogue Engineering spacers now incorporate a newly designed "step" on the back side of the spacer, allowing for adequate tools to aid in the removal of the wheel spacer, in the event of a stubborn spacer.
Another issue, when dealing with spacers of multiple sizes, is being able to identify them easily without taking out a caliper to measure them. To make things easier, the thickness of the spacer is now thoughtfully engraved on the front side of the face.
Our new "window" design removes the maximum amount of weight possible from the spacer itself. For example, our 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 our new design, you can have your spacer while adding minimal weight to the wheel assembly area.
Lug Bolt Information
What was always puzzling, was the availability of spacers in the marketplace that were always sold without lug bolts. Unless they were for a racecar with wheel studs installed, lug bolts were always an additional purchase. To make things easier, all Rogue Engineering wheel spacers include the require lug bolts. To ensure the highest quality, we source lug bolts from the same vendor as Tire Rack, the largest aftermarket supplier of wheels and wheel accessories in the United States.
After much work, we now offer BLACK lug bolts, of the same quality. The finish is not quite exact to BMW's OEM finish, but it's the closest that could be replicated. It is a black zinc, nickel finish which is both corrosion resistant and durable. More importantly, it matches the factory hardware!
