Default street and track alignment?

I have PDE camber plates and was wondering if any of you adjust your camber at the track or autox event. I've been told that any adjustment of the camber also effects toe. Is there anyway to easily adjust camber and still have a decent toe alignment, so I don't have to wear my tires out so fast?

The trouble is that whenever you set more negative camber, you'll also be setting the toe more inwards. That's exactly the opposite of what you're going to want for the track. Typically for the track you'll want more negative camber and more toe out than your street settings.

So if you're determined to make a camber adjustment at the track your best bet will be to adjust the toe at the track as well. You can make this easier on yourself by marking the tie rods to indicate your street setting and your track setting. That way, you'll be able to make the adjustments at the track without stringing your car each time.

The other thing you might consider is going ahead and running the negative camber you want for the track on the street but with 0 toe at all four corners. That way when you go to the track all you'll have to adjust are the toe settings. And as long you always run 0 toe on the street, accelerated tire wear shouldn't be much of an issue.

I am going through the same thing you are and have some information on NASIOC.

I disagree with this. When you move the camber plate in (say from -1.5 to -2.5 degrees) you add toe out (say from 0 toe to 1/4" toe out). I suggest reading these threads:

I don't know if this will help you but, I plan on running about -2.0 to -2.25 degrees of camber and 0 toe for the street and between -2.5 to -3 degrees of camber and about 1/8" to 3/16" of toe out for autox. Tire wear shouldn't be affected by running -2.0 degrees on the street as long as toe is zero. Search for posts by AndrewSS on iwsti as he just did the same thing as you.

Set your plates between hole 10 (stock) and hole 7 (about -0.4 to -0.5 increase in negative camber from hole 10) for street use. Get your car aligned to something like between -1.5 and -2.0 camber in the front, between -1.0 and -1.3 in the rear, and 0 toe front and rear.

When you go to the track or auto-x, slam the plates (hole 1) and you'll probably see between -2.5 and -3.0 in the front, with some toe out for added turn-in response. Before you go home, return the plates to the hole they were set at when you had your alignment. Bam, you're done.

My bad, I had it backwards.

I would just run -3 in the front with 0 toe and call it a day. About -1.5 in the rear with 0 toe would work well. I run -3.4* in the front on mine with no tire wear issues. As long as you have 0 toe and rotate the tires at oil changes you will be fine.

I run -2 front, -1.5 rear, 0 toe for the street. I move the camber in to -3 in the front at the track, which I know also gives me a little more toe out, but that's a good thing.

I think this is what I'll probably do. Thanks guys.

Would toe be affected differently if your plates were canted for caster?
