The thing is, basically, they provide more disadvantages than advantages in off road cars, unless you are a drag racer or really want insane top speeds from your vehicle. If that's what you're after, buy a shumacher fusion. It has a .21 engine and a 3 speed box, they do about 80mph out of the box. Buggies are off road cars and there's not much point going 80 miles an hour over bumps, you would not be able to control it.

That's why you're not getting much in the way of answers...capiche? [8D]
