the top three holes are the stock positions and i made it slightly wider, and reward. Ackeman is changed by the angle of tie rods to carriers i don't know why people talk about length. the arc motion of the bellcranks is what changes angles which in turn causes ackerman of steering.

I think you need to do some serious reading. You are wrong.

Pay particular attention to the discussion on angled steering arms. In the example given, moving A closer to B benefits the HF.

Ackermann is needed, but too much (ie Hellfire) is counterproductive. Compare any of the top truggies or buggies with the HF. The difference is obvious. No one runs as much Ackermann as the HF. The outside tire on the HF runs too wide. And remember, the outside wheel is more important than the inside for steering (more weight, more traction). A wider steering plate would work, but it would have to be fabbed.

I've done the mod. I know it works. Anyone that does not do the mod is doomed to have a truggy that steers like a tractor. But good luck to all you tractor drivers.
