This is the dual hardness performance bush 147P. Also visible is the cheap (Lemforder iirc) Audi TT bush which has disconnected from the centre tube which need replacement.
Two part top hat design
The black one goes in first from the chamfered side of the wishbone, then the yellow and then the steel tube.
Tapped in with a hammer

The wishbone and thus the bush is the other way up on the other side of the car.
I can't comment on their feel as I haven't driven with them yet.
