i was wondering if you put anything under the tires to let them slide easier on the garage floor

 

this is correct, well, not necessarily speed but the drive wheels produces flex when trying to push/accelerate the car forward. Same thing with the non-drive wheels which flex when it's being dragged.....

is it safe to assume that there's less flex since lowered cars with more camber have less road-to-tire contact, which is why most want the toe closer to 0?

 

you can use two floor vinyl tiles sandwiched together with grease in the middle, but becareful when all four tires are on it since the whole car might shift and give you false readings if your taking measurement from a stationary object. It's better to do two wheels at a time and not all four, to keep the car stationary. This is the reason why it's better to have actual wheel alignment plates since they provide slip but limited in movement, but they can be costly.

Lifetime warranty alignment doesn't seem so bad. If you know what you want from your alignment and have a basic understanding of the suspension geometry and suspension "vocabulary", you can get what you want from it.

 

That link is very helpful. Thanks.
If i can find someone who would like to be my "partner" to get alignment done in my garage, it'll be awesome. We can get the alignment done on each other's car.
I have some knowledge about alignment. The alignment guys are just stupid lol
i went to couple of NTB shops but they denied to do it since my car is too low for their crappy rack. I would need to remove the front and maybe sideskirts to MAYBE get on the rack.

 

Sorry man. Yes if you're down here I can do your alignment. Buying all this stuff for personal use isn't recommended. It costs quite a bit to just use it on your car alone.

 

For how much can you do it for?

Also i have a question. I got my alignment done. They hand aligned so i have no way of confirming but they told me that front and rear toe are set to 0. front camber is around -2.4 left and right. left and right are not exact but they are pretty close to each other. Less than +-.7 i think.
The weird thing is that the space between the fender and the sidewall is different from left and right. On one side, i can put my fingers through going upward. Can't move wiggle around the fingers much. On the other side, i can wiggle around my fingers between the space.
Did the alignment guy lie to me about the camber number?

 

front or back? because in the rear of the car there is slightly more room on one side of the car than the other. that and in the rear there is usually a height difference of a few mm from drivers to passenger side due to sloppy uper spring mounts.

 

its the front. I don't have adjustable camber arms

 

+/- .7 is a HUGE difference in camber settings, and even bigger difference in toe.

Thats almost a full degree of cross camber. Cross camber should always be within 0.2.

 

actually he said one side is -2.25 and other side is between -2.4 n -2.5

 

i measured the space, and it came out to be .188" difference left and right in space between the fender and the sidewall. how much camber difference would this be?

 

none. the tires is closer to the fender on one side of the car. its the same on z's and g's

anyone ever notice the rear diff isnt center under the rear of the car?

 

When i used to have SPC a arms, both sides were same

 

I bought a Tenhulzen alignment kit on Amazon for like $100. It's basically 2 aluminum plates and 2 quality tape measures with 1/32" increments. It has a digital protractor too for measuring camber. Works fine.
As far as I know you want at least a small amount of toe in or 0. Spec for our cars is 0.08 degrees. Toe in supposedly makes the car more stable at high speeds. Toe out is generally undesirable and wears the inside of the tires badly.
I went through a couple sets of tires until I finally thought I'd better check the alignment. It measured over an inch of toe out!! Set it 0.08 toe in, drove better, no more worn tires...
