Spacers are the quickest way to fix the sunken-wheel look on an E-chassis BMW. Push the wheel out 10 or 12mm and the stance changes completely. But the factory bolts were never meant to reach through a spacer, and short thread engagement on a wheel bolt is not a risk worth taking.
These Dinan cone seat lug bolts are M12x1.5 thread at a 39mm length, made for BMW E-chassis cars with the 5x120 bolt pattern running 10mm or 12mm wheel spacers. Steel construction with a black zinc coating, OEM-style cone seat, sold as a set of 10.
Matching Dinan Lug Bolts to Your Spacers
Two things have to match: thread size and length. Dinan's rule of thumb is that E-chassis BMWs use M12x1.5 bolts on a 5x120 pattern, while F-chassis (5x120) and G-chassis (5x112) cars use M14x1.25. There are exceptions. The F9x M5 and M8 and the F48 X1 and F39 X2 follow the G-chassis spec, and the E39 5 Series and E and F chassis X5 and X6 are not covered by Dinan's bolt range.
Dinan sizes this 39mm bolt for 10mm and 12mm spacers. Running a different spacer thickness, or no spacer at all? Choose the Dinan bolt length made for that setup instead, such as the 28mm factory length for no spacers. Dinan part number D220-0012. Sold by AutoTecknic, an authorized Dinan dealer.

Vehicle Fitment
Fits BMW vehicles within this chassis family when running 10mm or 12mm wheel spacers:
- BMW E-chassis with 5x120 bolt pattern (M12x1.5 wheel bolt thread)
Exceptions: not for F-chassis 5x120 or G-chassis 5x112 cars (M14x1.25), the F9x M5 and M8, or the F48 X1 and F39 X2. E39 5 Series and E and F chassis X5 and X6 are not covered.
Installation Notes
Fit these at the same time as your 10mm or 12mm spacers. Basic hand tools and a torque wrench are all you need. Check that your wheels use a cone seat before installing.
- Confirm your car is an E-chassis 5x120 BMW with M12x1.5 bolts and that your spacers are 10mm or 12mm.
- Safely raise the car, remove the wheel and clean the hub face.
- Fit the spacer, then mount the wheel and thread each Dinan bolt in by hand to avoid cross-threading.
- Tighten in a star pattern and torque to your BMW's factory wheel bolt specification.
- Re-check torque after the first 50 to 100 miles.
