To ensure the highest quality, Rogue Engineering 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, Rogue Engineering offers 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.
