Default DIY allignment?

i know DIY allignments have been covered before but i would like to see if this method works.

my main issue is that camber on my car seems rather difficult to set with the wheels on the car. im away at college all week, track car sit at my parents place 200 miles away. i know of quite a few shops that are capable of doing allignments like this (cars with lots of things that need adjustment, (camber, toe, caster). problem is, i can only be home on the weekends and NO ONE that i feel comfortable taking the car to is open on the weekends. geez i wish people were open for at least saturdays...

anyway. i planned to set camber myself, since thats the hard part. and then taking it to a regular allignment place to finish of the toe and caster.

what i want to know is if i can set the LCA's on jackstands (to keep the suspension loaded as if its sitting on the ground. and adjust the camber that way, rather then constant trial and error with little changes contantly taking the wheels off and jaking the car up and down.

so if i have the wheels removed and the LCA's sitting on jackstands will the suspension be in the same position as if the wheels were on and the car on the ground?

thanks.

I'm assuming you have a camber kit.

I've only had experience doing a diy alignment with toe.

heres what i did
measure between center of wheel to fender when the car is on the ground and suspension loaded normally

jack up the car and set on stands on all 4 corners
remove coilovers/shocks
use scissor jacks to raise the hub and set it at height as it was on the ground

The problem I see is that your suspension will not be loaded the same as if it's sitting on wheels. Your static camber will be different. If you set the brake rotors on jackstands that should be better at loading the suspension close to what it would be if it were on wheels.

hmm i drew some pics and did some calculations and you are right. with the jackstands furhter inboard then the tires (on LCA's) it will produce less force on the springs, and compress them less, giving a different suspension geometry. so if i leveled them out in this way when i put it on the ground with the wheels it would still have some negative camber.

but putting the jack stands on the brake rotors isnt a great idea (they rotate) and i dont want to bend them or anything with the weight of the car on them. unless you meant put the stands on the hat of the brake rotor? eurika, i think that will work since both jack stand and rotor hat are curved. is this what you meant?

obviously id use some lug nuts to hold the rotor tight to the hub (like the wheel would do)
