| Its a 20 dollar option when you order the seat brackets. A friend put a set of these seats in his C5 and I thought the single handle version was a little flimsy. I will have carpet in the car but I wanted to get these fit up so I can properly position the 5pt harness eye-bolts. The carpet should be "cut" a little away from where the mounts go on the front, but in any event there definitely shouldn't be that much gap. I did wonder about the floor pan being jacked up, but I measured both passenger and driver sides and they are identical
