I just had my alignment done. and I am not too sure how to read some of the data. I understand that Camber is the angle of the wheel/tire from top to bottom, Toe is the degree of pitch at which the wheel/tire points in or our looking at it in a front/back perspective. What I cannot figure out is the Castor...Does Honda or any mfg make Castor replacements? Also what is SAI, Included Angle.

History: Here's what I know about my 4G4D, I'm the 2nd owner. I was told by the original owner that the car was involved in a fender bender, judging from the numbers it was hit on the passenger side.
*
Findings: During my replacement of my springs to coil overs...I had a bitch of a time trying to reconnect the knuckle.
**
Anyway...I know that some of you are mechanics..please send me your suggestions at to what I should do..
*
I know that I will need a front camber kit. Which mfg. should I go with (Ingals, SPC, Omni/Skunk2?)...keep in mind that this is my daily driver.. I have heard of SPC as they have a wide range of products....

Anyway here's the attachment...let me know what you think I should or cannot do...

You have a caster problem on the right front. Don't worry about the SAI and included angle, those are just calculations from the rest of the stuff.
The caster could be due to something being bent, maybe the car hitting something. A google search will give you lots of information and pictures on alignment geometry, better than we can type here. Picture > *

I agree you have a caster probem at the right front. Here is a basic short course on alignment.

thanks...more suggestions please. I posted the real numbers...now you have a better idea.
they just told you whats the problem...something is more than likely bent or worn in your right front suspension...either lca, uca or knuckle...
on our cars you can not adjust camber or castor without an aftermarket part...
and you dont need a camber kit...-1.4 is fine...im at -2.5 and havent had any problems...

Gator thanks,
I figured that I had a bent suspension problem...I would like to find out how to go about figuring out what exactly is the problem, and how to replace the necessary parts that are bent. I know that there aren't any castor kits out there for Honda, which really sucks. But, I am just wondering too, if I replace parts will that solve the problem, or could it be slight frame damage..

Yeah defantly the caster is of on the right side
Could be some of the things stated above, and i also bileve it could be a bent subframe

well the first things i would replace are the lower control arm check it, then if that doesnt solve the problem, go for the UCA... otherwise swap the knuckle...if nothing solves the problem i would guess you bent the front subframe...
id start from the cheapest part first then more expensive...

So are you saying that those companys make caster kits? or are you stating that caster can be ajusted with the crossmembers they sale?
Do you know how many degrees -/+ they ajust?

Some alignment places can shift the front subframe and adjust caster. it costs a bit more, but it can really help. I'm not sure if you'll be able to even out a 2+ degree differential though. that is on the high side and suggests that something is bent. probably a lower control arm, which can happen if you hit a big bump or pothole.

Hey....DRDISCO69....Please tell me what you know....

I agree w/all of your replies though..I may have to start replacing suspension pieces. I hope that I don't have subframe damage though.I have huge feeling that my knuckle may be bent slightly...because I had a hard time getting the strut holder or fork back onto the LCA or Knuckle area. The more I think about it It just may be the knuckle as the castor is way off. but it could be another part putting stress at that point.

I think those are one and the same. A camber kit allows you to adjust your camber, for instance.
I don't know the adjustment range on those kits, but I would imagine it would be plenty for what most people need. I know the subframe I plan on making will have PLENTY of adjustment, in all directions.

I think something else would bend before the knuckle bent, check lower control arms, radius rods, mounting points, etc. Also a shifted subframe. Sometimes you can loosten the bolts on the subrame and move it around a bit to make up for small problems. I think you're a little far out for that, but it's good for fine tuning.
