This is still in the development stages. It hasnt' been decided upon, this isn't a group buy either.
Whatever ones will work, be cost effective yet produce good results will likely be the ones that get used. Why do we use Unorthodox or ASP UD pulleys? Why not shopko or A/C delco? They dont make them!
If N/A 'ers wait and get a full "kit" if/when one comes out, then they will have to choose. We will have to wait and see what gets marketed.
Don't you wish your car was as cool as mine? wait...it is? Go to hell then!
