Fixing to do the Shelby Drop to my 65

[Rapid]

How much negative camber occurs from just the drop? I am just trying to work out how many, if any, shims to leave out to get the best initial setup. The car has 620 springs with a 1 inch drop.

For you initial setup, start out with half as many shims. That should get you close enough to drive the car to the alignment shop.

Good advice. Half as many shims turned out to be just right for me

I just did my '65. I used the 1" drop 620 springs as you are and the shelby drop. I removed 1 shim from each side (2 per control arm). I ended up with too much + camber, and when aligned, they had to add shims back. I know each car is different, but that's how it affected mine.

The specs when taken in came in at (EDIT -1.5 degrees on each side. He set it at -.2 degrees). Some people say to run 1-2 degrees with the Shelby drop, but the alignment shop didn't recommend it on radials, not to mention, 2 degrees is very noticeable to the eyes and looks rather weird.

I was told you need to set it to the shelby specs not the original mustang specs. True?

Actually, you want negative camber in the alignment for good handling.
Somewhere around from 0 to -.5 is ideal on a street car.

Your car must plow pretty bad with +.5 camber setting

Doh, maybe it was .5- ? Can't remember now, have to check the alignment sheet. As far as plowing ??? How would .5+ cause plowing ?

EDIT- This is somewhat confusing to me, maybe because I dont' really understand it fully. But the Alignment report has Camber included twice.

It says:
Caster Left -.7
Right -.3
Camber Left .2
Right 0.0

FRONT
Toe Left 3/32
Right 3/32
Total 3/16
Camber Left -.2
Right -.2

Those are some messed up alignment specs. The sheet is a little hard to read, but regardless your car has a lot more potential.

 

[damannhw]

What specs would one want on a street driven car with coil springs and the Shelby drop ?

 

[2bav8]

Caster:
+1.5° to +2.5°

Camber:
0 to -.5°

Toe:
1/8"

I have these specs on my website for future references.
