They have the same blueish fabric but they are not like s14 seats they are wider and have more padding. I have an s 13 don't know how the rails on the s14 seats are. The 13 seats mount on the side and r34s mount on the bottom.

no I got a steal on the seats if I told u how much some people would cry I didn't pay the

Jdm tax I could get a few sets of 14 seats with the money in saved couldn't ask for anything better took a bit of cutting and welding but the results speak for themselves now if this rain stoped I could get some good pics to show u guys. I'm 5'10 and have no roof clearance problem.
