Roy, did you check out the touring seats? I actually prefer them over the base due to the lumbar support. They are basically the exact same seats, except it has leather, lumbar, power, and heated seats. But for some reason I fit better on those.

The touring seats are nice but they seem to bother my lower back after a while. It's not the softest seat. I haven't st in a base or Nismo so I wouldn't know what those feel like but the heated seats are a huge plus.

I actually get lower back pain on both the base and touring, I am on the bigger side! So the bolster kills me hahahah. The bolster pushes me further away so it is nicer.

Yeah roy's a big son a B*tch too lol. Im 250 at 5'8'' and the seats kill my lower back. Lookin to find a place near my apartment that sells sparco seats so I can test sit them. Heated seats are a huge plus but I want the plush comfort of a cloth seat. Try to sit in a nismo and then a base and you most likely will see the lumbar support difference.
