Centerlock Wheel Conversion
BMW E36
A centerlock hub adapter letting the E36 run 18-inch 13J Nissan GT3 Nismo wheels, with a wheel nut based on the Porsche 917 BBS design.
Running genuine centerlock wheels on a lug-bolt chassis means engineering an adapter that can take the wheel's full torque and clamping load without adding play at the hub. This adapter carries an 18-inch, 13-inch-wide Nissan GT3 Nismo wheel.
It's a two-part design: an aluminum spacer section paired with a steel threaded section, splitting the load-bearing thread from the bulk of the material for the best strength-to-weight balance. The wheel nut itself is based on the Porsche 917 BBS design — a proven, purpose-built centerlock nut geometry rather than a generic knock-off spinner.
Highlights
- Fits 18-inch, 13J-wide Nissan GT3 Nismo wheels to a lug-bolt E36 hub
- Two-part aluminum/steel construction for optimal strength-to-weight
- Wheel nut based on the proven Porsche 917 BBS design

Custom Wheel Spacers
Precision wheel spacers built in whichever style actually suits the hub — pressed-in studs, pressed-in steel inserts, or simple through-bolt — rather than one generic design forced onto every car.
