I've been looking for awhile at the new 2013's and am thinking of getting one. I've been dead set on getting the Performance Package but am having second thoughts. It will primarily be a daily driver and maybe just maybe it will make it to the track. Never been yet with any of my SHO's in my sig however I have aspirations of doing so. What I struggle with is the PP come with no spare tire and summer tires. Being a daily driver, I would prefer the spare and all season tires. What I like about the PP is the ability to switch of the traction control and you have a sports mode that gives it a little extra pep. Also the PP comes with different gearing and extra cooling. At some point I would want to get a tune, tint and lowering springs. If I don't get the PP, am I loosing out in flexibility or performance down the road?
