Hello Z People.
I just picked up a Sparco Evo XL QRT Seat with rails and a planted base. Getting ready to replace the factory seats in the Nismo. I'll let you know how it goes. Shipping from West coast to Texas was quick. The box arrived in great condition, Props to FedEx for that.
Tip: If you are going to buy this seat, you will only need to buy the side mount bolt kit. It has more than enough hardware to secure seat to sides and base. The seat rails themselves also have 4 bolts and washers included.

I didn't see large sparco seat install thread so I am putting this one together. I am a big guy. I am 6'3" over 200#, and a 38" waist. This seat fits me great. Super comfy and built right. I plan on doing the airbag resisitor mod. Parts are on order from Amazon for this. It's hot in Texas right now so bear with me on this. I hope to be able to work through this install soon. Updates to follow. PM me if you have questions.
I will be installing this in a 2014 Nismo 370Z. The factory seats for the moment will be retained until I am satisfied with the install. There will be seat parts available in the future for those that need them. Nissan wants entirely too much for replacement parts. Hence the Sparco install.
