Only really used one as a sim seat briefly. These are currently hard to come by as Recaro has stopped taking orders and back ordered a lot of their seats.
I also have 2x Recaro side mounts, 2x Recaro bolster protecter and 1x Recaro sliders for sale. My friend has an OEM electric slider with BK side mounts for sale for those that wants to install these in an F8X car.
Local in DFW, TX. Would rather not ship but can at buyers expense.
