Im coming up on the 100k mile mark. Currently at 91k. Other then the traditional oil change, and topping off any fluids under the hood, and new tires what else is suggested to be changed at 100k miles?

 

I recommend that you follow the 350Z maintenance schedule. If you do not have one they are free on the internets. Not sure if Nissan recommends replacing brake fluid but would add that to my list.

 

I am assuming you are not the original owner of the car.
Before making a list of what to do at 100k(this is not some type of magic
mileage number by the way where your car will change--many Z'S are out there at
175K +),I'd try to determine what has been done by the previous owners.
Have the belts been changed?Gearbox/tranny oil/fluids changed etc.
Then go from there per the service manual.
