Hi All,

66 Mustang inline 6 goes in the shop at the first of next week for a complete suspension work(stock parts). Going to consider doing the drop without touching new springs. What say you

Go for it.
Then set your caster to 2 to 3.5 positive with shims(no more than 0.25 difference side to side).
Set camber to -0.5deg to 0deg (right more negative than left to counteract road crown)
Toe should be 1/16” to 1/8”
You may need upper ball joint wedge plates if you notice the grease boots getting pinched.
Did the wife’s 66 and can tell you the handling is much better.

If you are keeping old springs, have them switch sides on your springs while they are out if you can as well. Most of our cars have been single driver for so long the driver’s spring gets slightly compressed- switching them is like rotating tires. Your ride will be a little more level with a driver in it afterward. Or maybe you meant you were installing new springs but not cutting them?

that's correct I was considering cutting them with no drop. New springs front and back. I'm putting in new upper and lower arms as well.
