Hi Pete,
Yeah I had a great Christmas and New Year, hope yours was the same.
The seats I would recommend highly, they were excellent. The only issue I found was on long journeys, I would get the condition known as numb arse, but it was only on long journeys. The cushioning wasn't luxurious, so after a while it would squash down so you end up sitting on the Carbon Fibre. I also found swapping them over (drivers for passengers) every couple of months helped keep them in good nick.
I just bought the seats from Demon Tweeks, when i got home I realised I couldn't mount them to the original rails. So I bought a set of Cobra seat mounts, which didnt fit the mounts in the car, and I ended up buying a set of Seat Rails from Buddyclub, these fit the seats and the original mounts in the car. Also a bonus is the sider, so you can move the seat back and forth reducing wear on the seat bolster, but at £150 a pop they wasn't cheap.
The rails I bought from Buddyclub were the super low ones, I would recommend getting those as the head room, even on the super low ones wasn't spacious. The seats still sat quite high.
