I would gladly trade my standard sport package rims for the black sport rims as those were the one swap I'd like to have had with my car from day one that wasn't on the car and they look amazing. But the one's you're talking about are sweet too (especially on the darker colors).I had to have the sport... definitely... kinda wish I had gotten the gray wheels (not the black 17's)
I would lower the stang, though I am in NY with some of the crappiest roads...suspension wise I've done just about everything but lowering. My exhaust is a bit of a custom job, the cats hang really low anyways.
I just want them both simple and clean, if the Mustang doesn't impress, I can get a lot of attention just from the Kona paint on the focus... it's a good combo. The stang is pretty loud and definitely demands attention lol
