Some people have posted pics on other forums showing sheetmetal damage and only light scratches on the flares. It almost seems like they're too strong and don't flex which pushes the body panel in more.
They don't look to bad on the ZJ's but I can think of lot's of stuff I'd rather have for 500US+GST/Shipping.
I'd rather lift my WJ a couple more inches than have to hack that much out of the fenders anyways.
