Managed to get a spare day to fit the new seat in yesterday. A lot more faff than I was expecting, not helped by me fitting the sliders upside down first of all ( ) but a huge difference. Interestingly the Recaro Pole Position sits a lot deeper in the seat than the Sparco Sprint, so I wasn't raised up by as much as I thought I might be once I'd put the sliders on. It rubs against the centre console as I've got the seat belt buckle on the outside of the seat (it can go inside too, the seat is recessed there specifically) as I wanted to give Jo as much room for her lady hips as possible, but a small felt pad against the buckle prevents any damage to the console. Sooooooo comfy, yet I don't feel any less supported than I did with the Sparco. It really was worth every penny.
Some crap pics before and after:
Sun is in totally the wrong place this morning for the Recaro pic, I'll get some better ones at some point. Looks and feels very OEM+ though, which is exactly what I was going for. Just need to save up for the other side now!
