remember the more you clearance the weaker they'll be so prevent that at all costs.
I call
on that statement. The amount you actually take off for clearancing is next to nothing. And once clearanced, they run at the same angle. I prefer to use IFS CV's because they are more common than the early ones and can be picked up for cheap. I run a clearanced V6 CV in the rear and a clearanced 4Cyl CV in my front for that same reason. CHEAP.
I think most people avoid clearancing them because they are either scared to try it, or are a liiiiittle bit on the lazy side.
Here's a good link if you wanna try it, takes about 2-3 hours for a newb:
