So when i am aligning outback struts on my 91 legacy sedan, how much extra angle in a camber bolt do i need? is a 1.75 degree offset enough or do i need to get a 2.5 degree or more?

 

 

thanks

could use an answer plz

for the equasion to be worked you would need stock specs for:

 

length of trailing arm

 

then the lift in inches

 

if you drop the trailing arms with the strut your okay. 1 degree is normal for most cars to gain/lose due to thrust. positive .5 goes to the front and negitive .5 goes to the rear since your going positive in the rear.... if you lift your rig 4" at with a trailing arm measuring 28.65" (30") your gain it 2 degrees per inch

 

NOW this is directly related to a arm and swing arm equations so having a trailing arm and strut makes things a bit more difficult to equate. you affect your caster more than anything else. if you drop your trailing arms with your strut you are golden if you put on bigger wheels remember you gain for every inch so go off of your stock specs, gain in wheel circumference is gain in camber unless trailing arm is depressed.

 

so not to run in circles... trailing arms mainly affect caster unless they are set at their own positive or negative "camber" degrees. take the basic 28.65"=2 degree gain/loss and cut it in quarters because the trailing arm does not have the camber change of an a arm it has about 1/4..

 

so a 4" lift with a 30" trailing arm and 27" tires (3" gain from stock tires) 1.75" offset would be a good answer

good info, thank you.

 

however this is not a drastic lift, I am just installing outback struts on my legacy, and was wondering if anyone who had also done it knew what kind of aftermarket rear camber bolt i needed.

ive read in fourns and they use these
