Dude, you got some tuff choices to make!
I guess its all a matter of taste. I didnt want something too loud so i stayed away from the chrome, but if i did get chrome i was gonna get these, there not too busy, sleek and attractive. I L L luv em.
Out of the ones you picked out i like the second one best.
I dont think you can go with 20s unless you recalibrate the speedo. not sure, but i think its computer related somehow. to make 20'* work without adjusting anything you would need like a half inch tire or something.
I got 18'* with 45s on them and it was a couple mm different from factory size of 60/16. Bout as close as i could get. it puts my speedo at about 1/2 mph off at 100 MPH.
