What's everyone do with seats in their M35? The standard ones look quite flat and not very supportive in corners. Anyone can confirm? So what would alternative options be? I take it theirs aftermarket rails so you could bolt in bride, recaro, sparco etc easily? Anyone know if V35, 350Z or any other performance Nissan seats would bolt in easily, whether using the stagea rail or the rail from the V35, 350 etc?
