I'm sorry I know this has been gone over on this forum before, but I can't find any threads to answer my questions. If I buy 4 of those zero-rate add a leaves, for the sole purpose of using them to relocate the axles, how much work is involved. I'm sure there is quite a bit more work to be done in the front, right? Does anybody know all the steps you must go through? And does the 2-3 inches you gain in wheelbase make any noticable difference to the person behind the wheel?
