elementwheels.com offers a few options; staggered and non-staggered. I'm thinking about going with a staggered set in 20x9, 20x10.5. something like this...

I may, however, need to purchase the tires from tirerack.com since element does not offer a pair in 255/40/20 front, 295/35/20 rear.
tirerack.com has the Michelin pilot sport A/S plus all seasons in those sizes.
another handy tire configurator.
