Default questions about alignment specs

Hey guys,

I just recently installed my Koni RSK kit and went straight for an alignment to see if I actually needed a camber kit.

The guy performing it printed a spec sheet and suggested I get a camber kit before I get the alignment.

Here are the details:

<U>Front : Left</U>
<U>Camber</U>
Actual: -0.9
Specified: -1.0
Range: 1.0
<U>Caster</U>
Actual: 1.7
Specified: 0.7
Range: 2.7
<U>Toe</U>
Actual: -0.20
Specified: -0.04
Range: 0.12

<U>Front : Right</U>
<U>Camber</U>
Actual: -1.4
Specified: -1.0
Range: 1.0
<U>Caster</U>
Actual: 1.1
Specified: 0.7
Range: 2.7
<U>Toe</U>
Actual: -0.16
Specified: -0.04
Range: 0.12

<U>Rear : Left</U>
<U>Camber</U>
Actual: -2.0
Specified: -2.0
Range: 0.0
<U>Toe</U>
Actual: -0.29
Specified: -0.04
Range: 0.16

<U>Rear : Right</U>
<U>Camber</U>
Actual: -2.6
Specified: -2.0
Range: 0.0
<U>Toe</U>
Actual: -0.11
Specified: -0.04
Range: 0.16

Can someone explain what all this means?

Also the steering wheel is off by a hair but the alignment shop told me he'll fix that when I bring it back for the alignment.

Thanks.

well, to update the situation I've already purchased and installed the rear Ingalls camber kit. I'll be receiving the front anyday now and installing those as well.

I understand the place that will do the alignment can just dial out the toe to 0 or as close to it but i'm an absolute suspension newb and have no idea what most of the sheet says.

Hopefully someone can explain what specified/range etc means.

btw, Ultra Rev 1 day shipment!

Maybe...
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Front : Left
Camber
Actual: -0.9
You have negative .9 degrees of camber at the time of the alignment testing
Specified: -1.0
Its supposed to be negative 1 degree of camber from the factory.
Range: 1.0
The camber setting is allowed an absolut range of 1 degree, meaning 1 degree negative or positive from the factory spec.
Caster
Actual: 1.7
Specified: 0.7
Range: 2.7
Toe
Actual: -0.20
Specified: -0.04
Range: 0.12
</TD></TR></TABLE>
*IF* I am correct, it looks like your toe is way off on all 4 tires, far out of the allowed spec range. In the above, your actual toe setting is .4 degrees out of the allowed range, which is from -.16 to .8.

0 camber = selling your car's potential performance short.

i think your camber is fine.

your only off by .4 on the front right. dont worry about trying to get the two sides equal. it really doesnt matter.

you could try to shim the rear right to add some positive camber. but again, youre not so far off from spec.

i would not worry.

Rear camber kit is warranted, front is completely unnecessary IMO. 1.4 is very reasonable and won't cause tire wear, you might loosen the bolts on the other side to see if you can eek out a little more there.

They can easily correct all the toe-in you have and get it closer to zero all the way around. That'll fix the off center or pulling of your steering.

thanks everyone... I assumed the front was unnecessary but came across a great deal on it. I'm probably just going to sell it rather than installing it.

what is the specified range for the rear?

if it matters, it's a '98 Civic

*edit

it's -0.2 +- one degree in the rear
