I know this migh have been asked but if I install the 2004 350Z rear suspension bar I know it will fit but will it improve handeling? Plus what would be a good tower bar to get fort he G35 sedan?

 

DMC,

If you're talking about the sway bar, they are exactly the same, front and rear, between the 350Z, G35 coupe and G35 sedan (Sport or Non). There may have been a difference in the '03 non-sport seden, but that would need to be confirmed. 2003.5 and later, you won't see any difference at all.

Hopefully others will respond regarding the tower bar. If you're referring to the front end strut bar (over the engine), it can't be done without significant modification; there are no mounts in the G35 coupe or sedan. Others on this forum have spent great effort on this one and came up empty handed.
