Congrats on your Z!
Here's my list. Hope you find it useful:
* Check tire pressures. Many have found theirs over-inflated from the dealer
* Are you gonna drive that sucker in the winter in Canada? Whew! You're gonna want a set of 18" winter wheels with 225 section dedicated snows, & maybe studs.
* A net for the back is helpful. I remember the first time coming back from the grocery store (any excuse to drive the Z, right?) and finding my groceries heavily rearranged
* Don't worry about engine oil temps unless you are consistently over 240. These things are designed to run hot. If you track it, get an oil cooler and a differential cooler if you have the limited slip rear (recommended for winter use)
* If you don't have the factory limited slip, replace the stock differential with a Quaife like some of the 350Z owners are using. Makes a world of difference in winter
* Put Rain-X on the rear window. Helps visibility in the rain without the ugly wiper from the 350.
* Wax your wheels. Makes it much easier to rinse/wipe off brake dust. The sport wheels are a pain to clean otherwise.
* Put a decent set of tools in the trunk, if you know what to do with them. I got a nice tool bag, which fits perfectly in the cut-out next to the spare.
* Get a larger oil filter and Nissan ester oil (or equiv). Change the oil after you finish your break-in period (first 1,200 miles)
* Do you need a front plate in Canada? Look for an aftermarket mount that doesn't require you to drill holes in the bumper. There are several US alternatives, one of which might work for you
* Replace the butt-hole reflector with a European fog light (if your car doesn't come with it). Saw some at thezstore.com
That's all I can think of at the moment.
Hope this helps!
