For those that don't know, these are absolutely the best mud flaps ever created in the history of mankind. They are also the priciest. These flaps are so sweet that I want to crap my pants.
So anyway, the have super good coverage. The fronts even wrap around the inside of the wheel well for coverage even when the wheels are turned. They have 2 mounting heights. On the lower of the two settings, the flaps scrape the ground when hitting hard compressions at speed or when turning sharply.
They come in many zesty colors that make me moist.
Installation: sucked. The flaps include instructions, but they're entirely in Japanese (they do have pretty pictures, though). I wasn't too geeked about drilling 4 holes in my front fender liners to mount the flaps, but damn if they aren't very robustly mounted.
Bottom line: save your cigarette money, take out a second mortgage, sell a child or two, but just get some. You owe it to yourself.
