    Designed and built by Eric Ruehl and Bob Roggy.

    These arms fit the D44 flat-top knuckles and put the tie-rod behind and on top of the front axle. Also incorporates crossover steering, too. /forums/images/icons/cool.gif

    Interesting thing about those arms is that they increase the Ackerman (toe change with steering). It changes from parallel steer (or close to it) to somewere near "classic ackerman" (toe out in steering...reverse ackerman is toe in when steering). This would cause the tires to skid sideways so much at low speeds and might help get rid of some of the "push" at high speeds. Fun stuff to mess with...I wonder if he even knows what he has done?

    wonder what wheelbase it is set up for.
    rear tie rod is the only way I can see to get good ackerman

    That might be strange...with the parallel steer that all the axles I have seen come with it doesn't matter what the wheelbase is when you do axle swaps. Those hi-steer arms might work well on a 100+" wheelbase and suck on a heep. Would be a expensive mistake!

    I dunno, having some ackerman is better then the negative(wondering if that is correct term) found in stock style.

    I tend to like more ackerman. So IMO these arms are a good thing. It would interesting to drive the same rig before and after to see what change it made.

    As a side note we used ALOT of ackerman on our little autocross car. The outside tire would turn about 30* and the inside tire about 45*. It handels assome (2.4g in the corners) in the tight stuff...and tracks that vette's fit thru it just flys!

    IIRC it was about 125% ackerman...maybe a bit more. It was adjustable and I'm not sure where we left it.
    0% being parallel steering and 100% being "classic ackerman" (ie where the lines thru the steering arm intersect at the rear diff)

    You might find this interesting (along with some other geeks)

    i just hope with the tie rod in the back it doesn't hit the front of the engine on uptravel. it looks like it might hit that pulley or the fan. ...might be catastrofic or i could just be tired.
