They are not the same brackets. Do yourself a favor and get B13 seats. I did a complete write up on B14 seats in a NX with LONEWOLF. The NissanNX server is down, so wait till tomorrow for a better reply. If you are under 5'10 it may be OK, but anything over and you do sit higher, even with NX rails.

i was just wondering, i just aquired a 200sx ser and i needed new seats in my nx

last time i checked brand new b13 sentra seats were only around $250 each :D

You should definately get the ser seats.

pretty white, your excellent write up fails to mention how similar the fabric pattern is to the original nx fabric. when you do that seat rail swap your end result
looks so close to the original that only a nx-er could tell the difference.
and i thought the newer seats were great. did 1400 miles on them and only had to be lifted out of the car through the t-top with the jaws of life once.....
kidding
they are just fine.
and it was great practice for when i had to do repairs on my p-10 touring
to do BLACK leather repair.
just took the skins off and took them to an upolstry shop for re-sewing.
20 bucks later, seats looked like new.

I like my p10 seats. I have the non-touring type in cloth. Two way adjustable headrest and a lumbar adjustment. They give a little more cush, IMO. They do sit slightly higher, however. I'm 6'2" and don't have problem on the street. Forget about helmet clearance for the track, though. Unless you like leaning waaay back, that is.

Thats true.
SE-R seats also match, but not as close as the 200SX.
I am going to see what happened to the server.....
