15MM (.59 inch) Wheel Spacers Adapters for BMW E39 5-series

The E36 and E46 chassis have a lot more wheel options than the E39 5-series. That's because BMW chose to use a larger center bore for the E39 wheel than any other BMW model and many wheel manufacturers are reluctant to make E39-specific wheels. These adapters are the correct E39 hub size on the inside and the correct E36/E46/E9X wheel size on the outside with a 15mm thickness. This is good because the E39 needs a low wheel offset and 3-series wheels are all high offset so a spacer would be needed anyway. A Hub Adapter Spacer is the perfect solution! You will need match the spacer to the new wheels (also taking the new wheel width into account) but call us for any fitment questions. Longer wheel bolts or wheel studs are required.

These latest generation of the Turner Motorsport Wheel Spacers represent a total redesign of the wheel spacer concept - a ground-up, clean sheet design based on our years of BMW service and motorsports. We took everything we have learned from our service technicians, customers, and race team crew and built the spacer to beat all spacers. We've been in the BMW wheel spacer business probably longer than anybody and when it came time to make our own spacers, a basic spacer design just wouldn't do. We had to make a spacer that is light weight (for lower unsprung mass), has a tough and durable coating to last through our New England winters, is easily removed (your mechanic will thank you), and is precisely engineered and manufactured for a proper fit on the hub and in the wheel. You won't find a better engineered wheel spacer on the market!

Extended Wheel Bolts

Required for all BMW wheel spacers is a set of longer wheel bolts or wheel studs. Spacers cannot be used with stock bolts. Our extended lug bolts are a very high quality and high grade steel lug bolt (grade 10.9). We offer two finishes to get you just the right look with your wheels - black zinc to maintain a factory BMW appearance or a bright zinc nickel finish to go with polished wheels. Zinc finishes are designed to withstand 700 hours of salt spray testing.
