I promise that the ackerman will make the difference with the shaved front top a-arm. I was able to drive the buggy with less effort. I even was able to finally set up my brakes and throttle the right way to allow the rear end to come around to match up with the quick turn. If you see a Mugen, Xray or Jammin you will see the top a-arms are narrow at the inside hinge point as compared to the Mayhem. I set mine up to shave 2.43mm to match the rear hub clips.
I will be glad to help in any way. By the way I did shave a little bit of the hub covers on each end of the front to allow for more turn.
Remember to use thread lock when installing the ackerman because there is not enough room to put nut under turnbuckle end.
