I guess I'll be the contrarian. I went with 20s and it's been fine so far, the sky hasn't fallen! Can I feel the extra weight? Nope. Is the ride harsher than stock? Yes, slightly. Do I feel like I lost handling ability? No, its still great in the canyons. If you're trying to get the style you like, take a look at 20s and don't have any regrets.
Personally however I think the OEM 19s look awesome with a drop and spacers.
