I agree with all the above advice, I also overpressure my tires and park each tire on a piece of that rubber mat sold at Costco for workshop flooring. I was told (by Dinan) if I left it on jack stands my suspension and shocks would suffer from hanging. I also add a half bottle of Redline Si-1 injector cleaner in the tank before filling up the last time. I do not know about the "winter plugs", I may look into that. I have been storing my roadster for well over four years and have had no problems. I do put it on a motorcycle trickel charger, wash, dry, wax, vacuum and clean her before storage. I also cover her with a good car cover.
