This is a wheel spacer like no other it is hub centric to your E30 on the back and has a larger hub size on the front to fit the Enki RPF1.
This makes using the RPF1 that much easier and safer. No more need for a hub centric ring that can fall off when changing wheels or melt under high brake temps.
There are two sizes for you to choose from 15mm & 20mm
- For E30 wheel hub inside bore dimension: 57.1mm
- For Enkei wheel outside bore dimension: 73.0mm
