If any of you have run the Yokomo 4wd you would know that the shock in the front or rear of the tower is a huge tuning tool. My rule of thumb is tracks with a bunch on 180's shocks in the front are best. A track with flowing sweepers shocks to the rear are better IMO. This is how I approach tracks with my wheeler and will be doing the same with the YZ. It takes minutes to switch it around.
