Thumbs up on the RockAuto purchases, that site is awesome. Has EVERYTHING you can think of for cheap too. (Except your superchargers and turbos haha).
I had Nexen N3000 tires on mine and pretty sure the base price for the stock size (245 x 17) was $130 or so. That was four years ago so maybe the price has gone up. As for struts/shocks, Monroe is a solid, slightly better than OEM choice. KYB is a good choice too for cheap. Check out their Excel-G struts. Best of luck and congrats on the purchase!
