Im not talking crazy amounts here. Im getting ready to tear PI apart again here soon and want to squeeze another 2-3 inches out of it. I like the ride and flex I have now, and dont want to lose that. Id just like a bit more clearance for the 14 wide wheels and next set of tires when the time comes. (39 Boggers.) I am also going from the stock shackle w/ a bolt to bolt of 4in. to 5-6in. (1/2 to 1in. lift from the shackles) So now to the question, does anyone think a 1 1/2in- 2in zero rate is too much. I can have these made up at the local machine shop. I dont see where more than the "standard" is that big of a deal. This is just a thought that has been rattling around in my head. I am not sure I am going to do it yet. I want to take a look at my caster angle and see how much the shackles will make a difference and maybe have a taper machined into the zero rates.
