NOTE: about "Ackerman steering", and "the long idler arm". This long,
(FAST RATIO) pitman arm we offer is basically the same arm used on the
AAR's and T/A's. The stock T/A set-up = long (FAST RATIO)
pitman arm and a short (stock length) idler arm. We heard that screws up the Ackerman
steering. So we put a car on turning plates to test that, and find out. Turning plates
or toe plates lay underneath the front tires and read turning angle
for each tire independently as you turn the steering wheel. Ackerman
steering, means that as you turn the steering wheel, the inside tire
turns about 3 or 4 degrees more than the outside tire so both tires are
arching equally, giving you, ~ "zero scrub". We
tested this in 3 different modes;....1, short pitman , short idler,(ie.
Your car, stock)....2, long pitman , short idler,(ie. T/A, AAR stock)....
3, long pitman , long idler,(recommended). RESULTS: 1) short/short = OK
ackerman thru out sweep....2)long/long = OK Ackerman thru out sweep....3)long/short
= OK Ackerman thru right hand sweep and OK Ackerman up to about 20 degrees
left. From ~20 degrees on out , the Ackerman gets exaggerated to ~10-12
degrees. We don't think this really adds up to very much in your overall
performance driving picture, because 20 degrees is a pretty tight turn
, more like a parking maneuver than anything else. But.... why not get
it as good as you can get it. Conclusion; If you can ..., use the long idler.
