I asked this question in regards to 52's. Boy, did I feel flamed. My reasoning was that the 52 swap moves the axle forward 1.5". If I install the zero rate to move the axle 1.5" back, this should correct this problem. Don't get me wrong, I realize that a crossover would be ideal, but for now I can live with push/pull. In the future, I will go with crossover. A friend of mine installed 54's in the front, and retains the stock push- pull stearing.
