gm g body ackermann angles

[futteen]

does anyone know what the ackermann angles are for a mid 80`s gm g body 2 door chassis is?

I'm pretty sure I've seen alignment specifications that used to include some kind of differential toe or angle measurement at a signficant steering angle.

I just made a few Google searches for alignment of a 1985 Monte Carlo and only cam up with the straight ahead settings.
Might need a factory shop manual for the good stuff.

i contacted umi performance they said they will provide me with the angles but a friend in texas told me to really change ackerman on the car id need longer of shorter pitman/idler arm but no one knows how much longer/shorter and if the outcome is good or bad so yeah back to square but me and my friend in texas discussed a quick and easy way of going from street friendly camber/caster to track day camber caster and adjusting the toe in between the two

and with in mind ill be using adjustable upper control arms i wont need the shims so i can just add one piece and tapered shims to find the right angles

Hi futten,

What are you looking to achieve?
Have you seen some of the other threads that talk about when Ackerman is, isn't, or might be important?

was trying to achieve improved angles because in norway it would be easier to get wider wheels and wider fenders approved if i can prove that the modifications improve the steering geometry but i might still have a chance i will talk to the norwegian dmv on monday but i would also like to actually improve things because as you might know those chassis arent all that great to begin with

Another strong source for G-body information is Mark Savitske at scandc.com (use the phone). Tell him I referred you.
