For Audi Sport Quattro
The Sport Quattro could be ordered with 4 spoke steering wheel with big 4 ring logo, shared with common 80 B3 and 100 C3, and with the 3 spoke Nardi wheel, Audi Sport badged.
This spacer is to bring the OEM 4 spoke wheel 5 cm closer.
Its main feature is that it replicate the OEM splined shaft/bore fitment, and has a specific shape to accept the horn ring from the steering wheel which is simply pop-out.
It compensate the lack of depth adjustment of the OEM steering column.
Fitment is 100% plug and play and reversible.
