General
Identifying 18-inch Turbo wheels (Technologie wheels / hollow spoke wheels) with the dimensions 9J x 18 RO 52 and 10J x 18 RO 65 (RO = Rim Offset) is only possible when the wheels are disassembled.

These wheels can also be fitted on the 911 Carrera (993) and the Boxster.

Turbo Look wheel: rubber valve
1 screwed-in steel valve
2 rubber valve
