I won't even say it.....but your gonna hate the spilt 4...I have it on mine and I dread it every day....forward next time.....but progress is looking good though.
I hate the 50/50 4 link also, had to learn the hard way. I had to much pinion angle when aired up. I cut it off and moved the upper bars forward. Only have about 1 degree in pinion angle change now.
I'm not talking about the angle. A 50/50 setup will not deliver power correctly to the frame. a Full reverse (although still not great) will work better than a 50/50 setup. However you should try to always run all the bars forward, or at least in the same direction.
