You only see 20s on show cars or wanna be show cars. 17s and 18s are more common for folks that was to run big rims. But I've seen quite a few of those end up going back to 15s for a better ride. The large diameter rims make for a harsh ride.
Bronze would work well also. I've been modding on the cheap though. My wife has trouble seeing me spend much on a DD when we have 4 vehicles to keep rolling. I picked the springs up used for 120, shims for 20, and the rims came on it.
I'd like to do a suede headliner with door inserts, A & B piller, etc.
So far it has been cheap to maintain. I see why all the Yota heads are so big on their rides. I figure it is half the cost to operate as my Dodge, including maintenance, fuel, parts, etc. The gap widens when I include replacement cost.
