Will seats from a 2006 fit without modification in a 2001?
 

I'm new to this forum but am a long time S2000 owner (2001 Silverstone over Red, owned since 2002)...would love to "upgrade" the seats with a bit more cushion as my advancing age dictates a bit softer "rear end" ride. I understand that the 2006 and newer model years had additional cushioning and support in the seats...is it a viable project to put these in my car? Looking for the red leather and trust that the red will be a close match color-wise to my car, but am more concerned about the fitment with slide rails and other interior components.

Thanks for your help!

The driver sides are exactly the same, but the issue will be the passenger side.

The 06+ passenger floor is different than the -05.

So you need new rails to match the earlier year s2000s.

Thank you for the info...what about the 2004 or 2005 seats in a 2001. They also appear to be more supportive. My major issue is sciatica, where the seat is just too hard for longer trips (3 or more hours)...this happens when you get older and still want to have some fun :)

My wife made me a cushion 5" in diameter and 12" long that fits between the bottom and back of the seat. Works for my back.

2004-2005 seats should bolt up on an 01 no problem.

You could also just take the rail off your car and put it on the 06+ cushions. There isn't a difference in the actual seat cushions just the rails (I speak in terms of the way it all bolts up)

Weird, I swapped 2008 seats in my 2004 with no issues at all.
