As per title, just got round to doing this and s3 seats need bolts whereas the octy seats use nuts at the front fixing points....

Any idea for those who have done it already?

Im sure its an M8 thread and about 20mm long iirc

Yeah, as above M8 thread and around 20-30mm should be fine. They're heavy bu**ers the S3 fronts!!

Thanks guys, all sorted now, yep they are on the heavy side!!

My car is quicker without them :-P
