quick question for you.

My freind's car toe setting is as follows:

front left toe is -.04
front right toe is +.02
Rear toe is 0.

Should the left front toe be adjusted closer to +.02 or is it close enough?
I just wanted to make sure his setting is not off by too much and have excess tire wear.

Thanks in advance.

 

I guess no one knows?..

 

You guys only answer stupid questions like " what is the best spring?"

Basically what I am trying to ask is the .06 degree difference in angle is ok or not.

He's just wanting a second opinion.

 

I would never roll with a setup that put toe-out on one side with toe-in on the other. I prefer a slight bit of toe-out up front (both sides of course) but if I didn't, I would put a slight bit of toe-in on both sides. Reason being, if you put it exactly at 0 you are always transitioning between toe-in and toe-out and it's less predictable than having just one or the other...

 

Thanks for the reply.

So what you're saying is he should get the -.04 adjusted to where it's +.02 toe out?

My other questions is which one is considered toe in or toe out?
The +.02 or the -.04?

BTW, when a tech did my alignment he set the toe as +.01 on the fronts.
I don't know why they left his like that; one side is negative and the othe is positive.

 

cause they didn't know what they were doing?


camber can be adjusted differently from one side to the other when you don't have the driver sitting in it. but the toe shouldn't change with sitting the driver in the car (i guess it would be like bump steer if it did), thus the toe settings should be symmetrical from one side to the other.

 

EDIT: Indeed as stated below toe-in is negative and toe-out is positive. I thought so too but I second guessed myself and looked it up on teh internets...

 

I thought it was the other way around.

I thought negative toe is where the front part of the tire is closer together than the back part of the tire.
Like so :
/-\ <----this would be negative toe (toe in)
II
I-I

\-/ <-----this would be positive toe (toe out)
II
I-I
This was my poor attempt at duplicating a car from top view.


Please correct me if I am wrong.
Thanks in advance.

 

toe, as I recall is measured in mm or in not degrees.
The spec on evo's is 0 +/-0.08" so your toe is still in spec. However, it would be a good idea to have them both the same at 0 as it is the stock value, or anything else that suits your fancy but the thing is to have them both the same value.
While you're at it, check the camber before you set the toe. If you have the toe set up and change the camber, you'll have to do the toe again.

p.s. I'm not a suspension guru, but iirc, negative toe is toe in and positive is toe out. In = front of tyres pointing inwards.

 

I just confirmed with a alignment tech..negative is toe in.

He just went back to where he got his alignment done and asked them to change the negative toe to match the +.02 but told him it's kinda too late.

He'll have to go back there tomorrow.

Thanks for the help guys.

 

Toe can be measured in either, but yeah the U.S. Evo manual specifies inches.

 

mainly a lenght dimension is used though, cos it's easier to measure and you can do it with a tape measure if you have relatively new tyres and are stuck in a jungle or something

Then you check the steered angle at full lock on either side and that's be in degrees. You'll probably need some kind of McGuyver type guy to measure that in a jungle though...

 

thanks for the help everyone.

BTW, he is still trying to get the toe aligned properly and the place is giving him a hard time about it.

They keep telling him it's within spec.

 

You have to look at the total toe and that is -.02 the only thing this setup will do is make the steering wheel slightly off center. Ideally on the Evo you want 0 toe.

 

That's a PITA cos you can't really argue with that. It is within spec. They're really only obligated to get the alignment to be in factory spec and tolerances and that's that. That's the difference between a good shop and an average one. I'm sure if you take it to a more reasonable or performance-orientated place that will understand that people like us are crazy about stuff like this and are equipped to appropriately to cater to our needs.
