I'd HIGHLY suggest it, cause your gonna be front end heavy from the motor and your stocks'll be put to pressure's way past factory specs.... at least get the fronts.. rear will last for a month or so.....
Flipping the ball joint is about 3 inches. If you put the 2 inch drop coils you will probably get aroud 1.5 to 2 inches. That is pretty low! I would just do the balljoints and then see if later on if you want to drop it more along with the back! Get some pictures up here when your done!
I was referring to extending the shocks out the bottom of the control arm to compensate for the coil spring being shorter, instead of buying shorter shocks. a 3" extension, if there is such a thing, would hang the bottom of the shock far below the control arm.
Gotcha, cause I had my stock shocks in for a while until I got the shorter ones and just had them bolted to the stock location. No need to change the mounting location. Wasn't sure why you said they would get hit by anything in the factory location.
