I am not usually a fan of anything bigger than 19" or chrome on a Legend, but your coupe looks better than most w/ 20"s that I've seen. Are you lowered? I think if it was just a little lower it would really set it off!
Nonetheless, let me be the first to say it looks great!
To each is own, I like the rims just think they are bit too big, plus, that is a large rolling mass, the inertial forces increase and they would probably cut down your launch speed (reduce the feeling of initial torque), then again what do I know, these are just my "theories".
I think it looks real good. Did you have to raise your car or do any modifications or such to fit them on there? I was thinking of throwing anything from 18 - 20's on my 94 legend sedan. Just wondering if im going to have to do any extra work to do this...
