stock or offset bushings

[leo 3000]

for the upper arm bushings
stock ones or the offset ones, anyone have a issue not getting enough camber on stock
on my b body i have the tubular FF ones. and to my knowledge they are made to give more negative camber
thank you

on for Abodiesony there a post on it and says to install in certain way to give pos camber
why would you want that, im thinking neg camber . so would you install the bushings so it moves in arm towards engine?

It is my understanding the offset upper control arm bushings are to compensate for "sag" of the structure the upper control arms mount to. I first heard of this situation on big block Chevelles of the early 1970s, but later discovered such also happened with 1955 Chevies. So the offset bushings have been around for ages, for many cars. In some brands of suspension bushings, the offset ones are all they sell, last time I looked.

Many aftermarket upper control arms, especially the tubular ones, are engineered to provide more positive caster than the stock ones can provide. Caster and camber are related, but different "angles".

Any guidance from Firm Feel?

Just some thoughts and observations,

thanks will call and ask , the alignment guy was saying keep it stock and see .
tough call. they could not align it the lower cta bushing were so wornout
now have new ff t bars and bushing, and i reinforced the arm with a plate at bottom

Positive caster will help with highway steering stability and return to centre.
What car are you working on?

When using modern radial tires on the rear wheel drive ’50/’60/’70’s Mopars, front wheel alignment can/should/needs to be adjusted for more and better steering response and overal safer handling of the car.
The following chart shows alignment specification values for various driving styles which can/should be provided to the alignment shop.

Driving style	Camber	Caster	Toe-in
Sunday Cruising	-0.25°	+1.5°	1/16" to 1/8"
Daily Driver / Street	-0.5°	+2.5°	1/16" to 1/8"
High Performance / Street handling	-0.75° to -1°	+2.5 to +3.5°	1/16" to 1/8"
Autocross / Circuit track racing	-2.0° to -3.0°	+3.0 to +4.0°	0" to 1/16" **
Dragracing	0°	+1.5 to 2.0°	0 to 1/16" *

this seems right but , wondering can i achieve with stock bushing .5 of camber and 2.5 caster
