So here is the deal, I'm right in the middle of my SAS and I'm going to run the shackle mount under the frame so I can run a flatter spring ( toy rears ) However I've talked with the guys at FOOTHILL and they say do not do this. I have also heard guys talking about their front caster getting all out of wack. Whats the deal ?? I guess I'll try it, and if I don't like it I can change it.
