well i got my"05 350z spring with 3000 miles" today. Question is, I remember my 03 springs saying nissan on them and some #s. These springs do not say nissan anywhere and have no serial #s. Do the 05 350z OEM springs not have the nissan/serial #s? Just want to make sure my 05 350z springs are legit. They also look kind of on the small side. Someone please assure me.
