Drivers seat in my 90 moves slightly back and forth under accel/braking. Took a quick look to lastnight and it appears that there is a bit of lateral play in the track, as well as some slop in the hollow pin that is just below the seat bolster. I can confirm that my seats, are in fact, still bolted to the floor. Also, the seat does not appear to be coming apart internally. Is this a common problem, and is there a fix besides buying a set of Sparcos?
