Alright, I'm new here-I just made this account today. Please don't castigate or emasculate me, but I know very little about this car. I'm just here to learn!
That being said, I've recently been given a 2011 GT500 by my grandparents. It has about 47,000 miles. The car isn't stock, either. It was my grandmothers mid life crisis, and they bought it used from a Ford dealership. They know very little about cars, but my grandmother loved it because "it had snakes on it and it was loud."
Anyway, she's tired of it and has gifted it to me. Here's what the dealer told us was in it: SCT tune, headers, exhaust, intake, and pulley. We have done nothing to it but change the oil, and I bought an aftermarket air filter for it.
How soon should I change the spark plugs, or should I at all? What tires would you guys recommend for daily driver with an occasional drag race? It's currently running Pirelli P Zeros. What other checking/maintenance should I do to ensure its operating at optimal efficiency and full power?
Remember, I'm new to all this and will readily admit ignorance. Any kind help will be much appreciated!
