Put mine on Saturday morning ... washed and waxed the beast the next day. Wow, all of a sudden, my hum-drum Civic is getting noticed by others on the road.
jthistle, I like yours too. Yes, I suppose I wish they didn't stick out so much (I noticed the same thing almost immediately) but I figure they are stronger in that shape. Flatter 'pizza pans' would have to be heavier to have the same strength, I think.
If/when I get real wheel skirts, I'll probably remove the rear moons ... and either sell them or have a spare pair.
