Just noticed on
2015 Nissan 370Z® Specs & Pricing | Nissan USA
that the Synchro Rev and LSD are only available on the 2015 NISMO. I.e. the Touring with Sport Package is no longer available as with the 2014. I haven't checked all the specs, but it looks like Nissan is retrograding the other models to force enthusiasts into the NISMO variants. Boy, am I glad I got the '14 Touring with Sport Package for everyday driving!
*Correction - I was mistaken. Both are available on the Sport and Sport Tech, but not on the Touring model. Therefore, you can't get a Touring model with a Sport package as with the 2014. I'm still glad I got the '14 Touring with Sport Package for everyday driving!
