Vorshlag has a variety of wheel spacers for the 3 series BMW and this 15mm size is our newest offering. These are for those instances where you need more than "just a bit" to clear that big wheel tire combo, and we used them on several BMWs already. These spacers are CNC machined from 6082 billet Aluminum and have the correct 72.5mm BMW hubs for a perfect hub-centric fit on 5-lug E36, E46, and E90 3 series BMWs. Sold as a pair. THESE DO NOT WORK ON AN E30 M3.
Comparable to other name brand wheel spacers - heck, Vorshlag will be a name brand wheel spacer supplier before too long! Built to Vorshlag specifications by the same Italian OEM supplier that makes our lug nuts; they are a fully ISO9001 compliant manufacturing facility with materials traceability, etc. These are some of the highest quality spacers for a BMW that money can buy.
Note: Don't forget wheel studs - you need at least an 80 mm wheel stud to use these spacers. Our 90mm studs would work as well. Shipping weight 2.5 pounds, in a well padded box.
