On the Infinitihelp.com web site the suspension on the sport option appears to be different from everything else.

The term they use is "unique front suspension geometry, tuning".

No idea what this means in practice. Many articles talking about this type of tuning but nothing explains Infiniti's implementation???

 

So... I will assume no one can speak to this issue!

or...

No Infiniti insiders here?

 

sounds like marketing fluff if you ask me
