Hello Adam!
There are lots of suggestions on the internet on how to prepare your car for winter storage and my suggestions will certainly include many I took from those sources. Since I have owned my '71 Z for all of it's 50+ years and it still runs and looks good with 190K miles on the clock, I figure at least my methods must be working. I would first suggest though, if you can, try to run and "move" your car at least once a month if you can, even if it's just up and down your driveway to avoid the salt and sand. This gets all those working parts like bearings, universal joints, seals, etc., re-coated with grease or oil. Other suggestions:
1) Put her away clean, inside and out. Washed and waxed
2) Cover the car with a good soft fabric cover if garaged.
3) Over inflate the tires by about 5 PSI to help keep the tires from flat-spotting or place the car on stands.
4) Change the oil and filter before storage
5) Battery - Either disconnect your negative battery terminal (my method) or use a "battery tender" if you don't want to have to reset any electronics in your car (my old Z has none). Don't use a battery charger though for this as it can overcharge your battery and cause an acid mess under the hood.
6) Very Important - Fill the gas tank with fresh gas along with a gas stabilizer, especially if you know your car may be laid up for more than 3-4 months. Run the engine with stabilized gas" for about 5 minutes to make sure it enters the entire fuel management system.
7) Make sure your engine coolant is in good condition.
Protect your car from dings and dents if storage is in a crowded "busy" garage. I use large pieces of cardboard placed on one vulnerable side of my car against the car cover.Some people even place their car over a layer of plywood or plastic to keep moisture from their concrete garage floor attacking the bottom of their cars. Hopefully you have your car garaged over the winter which, in itself, is a big help in preserving your precious Z car.
Good luck and I hope to ZEE you this coming CTZCC season!
