It is grossly overpriced. The full kit is $1,799 which is absolutely rediculous. IMO the front grill is atrocious; the sideskirts are nice but there are MUCH better designs out there for Honda Accord's that you can use on Explorer Sports. The rear bumper looks the best out of anything, mostly a half-assed attempt to make an XP8 bumper.
The site that sells this kit is Extreme Dimensions. The page for this kit can be found here. This is my photoshop attempt at color matching the kit with the car:
The second chop especially sucks, I did both in about two minutes. But the first gives a better idea. It's hard to work with since you have a dark blue background and a dark blue Explorer. It all just blends in.
Rear bumper: $625
Front bumper: $625
Anyone who pays that much money for this kit, especially for the sideskirts is a moron.
