Caster/Camber/Toe? 70 Roadrunner

PurpleBeeper · Apr 3, 2019

What are the stock specifications for caster/camber/toe for a 70 Roadrunner? My shop says their records only go back to '79 or something like that.

I'm using this car as a long-distance cruiser, so if anyone has suggestions for something slightly different than the stock specifications, please speak up. Thank you!

This is the recommendation when using modern radial tires and it's great. I recommend it often but is not the factory specs. You can read the full article here:

I guess a guy can always look at his Service manual for a specific make/model...
if running stock tires.

Serious question with that, since I have goodyear speedway bias plies on my Bee. Would you actually go with the old specs or somewhere closer to the table above that everyone seems to be striving for with radials?

Probably see what stock looks like compared to above specs and compromise.

I think I'm going to go with 1/4 degree negative camber, 2 degrees positive caster and 1/16"-1/8" toe-in. I'm relying on the chart basically. All I know for sure is a little bit of caster is good....and I do plan to grandma drive it (yeah, we'll see how long that lasts).

Actually - as much caster as you can get is better unless you have manual steering and have difficulty with tight turns.

I recall that the original factory specs used different numbers side to side to take into account the crown of most roads, to prevent wander on the old bias ply tires.
Even toe being out can make a car wander on the old style tires.
