Re: hi steer questions
The Ackerman angles mentioned are well depicted in your second pic of the Breeze setup. (The orange
arm) The stock tierod, the part that matters to Ackerman, is set well outside the kingpin axis. The
breeze is set well inside. 0 deg Ackerman would be somewhere between the two.
Many race cars run 0 deg Ackerman, but they are steering with the throttle and want the front wheels
pointing the direction they want to go, a very different and extreme way of driving.
If the tie rod was behind the kingpin instead of in front, you would want it about as far inside as you
see the Breeze arm positioned, only behind. The Mercedes arms are about the same deal and angle
as the Breeze. The Breeze gets away with it only because its the drag link instead of the tie rod, no
Ackerman is involved. The Mercedes does affect Ackerman since it also positions the tierod.
The thing preventing a correct Ackerman angle with Hi steer is the disk brake rotor and tire/rim is in the way.
To get it tha high, it gets into interference with those parts.
