I took my car to my local Firestone today, for a set of FR380 tires, 195/75R14's. My car is a 66 Convertible, 6 Cylinder.
I also wanted to get the front end aligned, since the car had a pretty major pull to the right and with the old bias ply tires, really handled poorly.
Lucikly(or so I am thinking), they didn't have the necessary shims to do the correct alignment. They were going to align by the Ford factory specs for caster/camber/toe.
I have done enough reading to know that it seems that the Ford specs for alignment with the newer radials and 45 years of knowledge are not maybe the optimal specs.
Currently, the car is pretty out of spec for camber/caster and toe. See my attachment, it is of the shop print out of the current specs.
Here is something I found here on this site that are some recommended settings for my 66 for an alignement. I am going to assume that these settings would apply to the 6 cylinder model also(but not sure of that totally, because an 8 Cyl would have a heavier front end):
Please align to these specs ď1960-1966 Mustang and Falcon Performance Alignment with or without UCA dropĒ.
These specifications are in order of importance. 1. NO more than .25 degrees difference between driverís side and passengerís side. 2. +2.0 to +3.5 degrees caster. NOTE: for cars with Adjustable strut rods. Please attain as much caster as possible using the shims (at least 1.5 to 2.0 degrees), and then use the adjustable strut rods to increase the caster and make the sides the same. Also, please note that the caster difference between the driverís side and passengerís side needs to have no more .25 degrees difference prior to the adjustment of the strut rods. 3. -.5 to 0 degrees camber. No positive camber, please. There is no problem having a slight variation from driverís side to passengerís side to account for the crown in the road. 4. 1/16" to 1/8Ē toe in If you run into any problems attaining these specs, please call me (your phone number here). For my car, would it be reasonable to use this as a guideline to get the alignment to something driveable, versus the Ford specs which is what they were going to go by, if they had the shims today. Maybe this delay is for the better, if I end up with a better alignment using the above?
