I apologize if this has been asked before (I searched) but why do I need to get an alignment after flipping my stock camber bolts from the -1 to the -2 setting? I don’t understand how rotating the tire along the axis running through the middle of the tire going from the front of the car to the back of the car (camber) can affect how the tire is positioned on the axis running through the middle of the tire going from the ground to the sky (toe). Here is someone’s chance to wow everyone with their superior suspension know how (maybe). I don’t mind spending the $70 bucks for an alignment I just don’t want to go through the hassle of finding a competent shop and dropping my car off there when I could be driving it.

Yes. Toe is greatly affected when camber is changed. On some cars you can adjust camber without worrying much about the toe. With the Evo that's not the case though.

 

Thanks for responding. I'm still confused as to the mechanics. So to reverse it, would adjusting toe affect camber?

 

I think I can answer my own question now after some brainstorming with a coworker for the sake of any future searchers. If the suspension is set up to have caster, that is the suspension is mounted at an angle towards the back of the car which increases camber when turning, then adjusting camber would affect toe. I don't fully underestand this yet but that is our best reasoning.

 

I believe that it does change things like the toe and castor when you just mess with the camber.

I wonder if you got camber plates could you independantly dial in more negative camber without worrying about the toe?

 

I don't see how camber plates would affect toe more or less than moving the camber bolts.

 

Camber plates affect toe as much as the cam bolts. The question about toe affecting camber, toe will but very very little compared to camber affecting toe. The rear suspension seems to be a little more touchy compared to the front of the Evo but then again it isnt an isostrut design its multi link so there are lots of other engineered variables there.

In the rear they must be set together in the front toe is last.

 

New question. Can I adjust toe by simply comparing the distance between the front of the wheels to the distance between the back?

 

Yes, sort of. But you need to be wary of thrust angle. And be very very careful with your measurements + numbers. There are some toe gauges available that make it a lot easier, but the only way to account for thrust angle as far as i know is the good old string method (if you want to DIY).

... and what is thrust angle?

awesome, thanks.

 

Setting toe is an easy DIY project if you have a gauge that provides very accurate measurements. Google "Trammel Bar". You can make one out of scrap lumber.
