Really just comes down to preference on the front. Just remember that not all kits will allow you the same range of movement. Ingalls will allow somewhere around 1degree of +/- movement while others like like Progress I believe will only allow postitive movement. Currently Im looking at the skunk2 fronts since theyll allow up to 6degrees of +/- adjustment which is more than you should ever need. The rears you can buy a custom kit or just make your own out of longer bolts and spacers doesnt really matter.
