I saw my first "street" JKU in person today.
Super dark tint
Black w/Black hard top
18 or 20 inch wheels, black with something shiny in the middle
"low profile" type tires that looked to be in the 305 range, street tread
probably no lift, but leveled out
Then I got to thinking, maybe the OP would like to go the other way with that cash and build an off-roader. After all, unless you take a big plunge on the $$$$ you're not going to make it very "fast" or "quick", like a sport touring car.
And yeah, he could still run 20s as long as the tires were 40s :-)
