Like DHCrocks mentioned, you have the sport coupe.

ALL 03-04 6MT coupes are sport coupes because they all have the 18" wheels w/ summer tires, LSD & Sport suspension.

As far as 03-04 5ATs there are 2 trims, Sport and Non-Sport. If you bought a coupe with 18" wheel & tire package you got the LSD and Sport Suspension. Otherwise the Non-Sport coupe comes without LSD, non-sport suspension, and 17" wheels w/ all season tires.

 

yes you do have the LSD

 

I have 17" wheels, non brembo and on my manual it says sport coupe... so I dont have the LSD?

 

Wasn't there an issue where if you bought the premium package with the 5AT, Infiniti had said it came with LSD but it in fact, did not. Only the sports package?

 

so the 04 does not have a sports suspension option correct?

 

How can you add LSD if you don't have one?

 

This is not true. I have 18" and I think LSD(how do you kno) on my 04 but I do not have Sport Suspension. How do I know? I called Infiniti with my VIN # and they said I don't have sport suspension.. I can feel it too. My car has a rougher ride than my previous 03 + a lot more roll on corners..

 

Getting a pumpkin from a manual is a pretty good way to go: http://www.my350z.com/forum/showthread.php?t=291624.

 

The sport suspension is ONLY available for 05+ models. The 03-04 models all had the SAME suspension regardless of wheel size and/or transmission. On the 5AT, if you get the wheel & performance package, you get the 18s w/LSD. If you don't have 18 inch wheels (stock), you don't have an LSD.
