Rear toe

Anyone ever run more than 1/4 (total) rear toe? Opinions?

1/4 inch? or 1/4 degree?

1/4 inch. Sorry.

I errored and set my rear toe incorrectly. I have believe I set the rear toe to about .315 inches total. This seems to be over one degree. The spec, as best I can surmise, is .45 to .65 degree total. The car feels squirmy, and I am thinking this is the cause. I'll string of up again tomorrow, and report here.

I used to run about that much toe-out on the rear of a Subaru. Triple that much toe-out on the front, to counteract the absurd amount of positive camber that Subaru gave it.

Must have done something right because I could probably have calibrated a T-square on the tire tread at all four corners.

Toe in or out ? Big difference in handling.

Toe in. I was planning on just having it done, but the craziness of this place convinced me to have a go at it myself. ;-)

What car? makes all the difference in the world.

'98 M3 for autocross I used as much as 1/8" / side. On the Radical 1/16" / side is perfect, and I can run a little less, like 3/64", but at 1/32" it's not getting power down out of slow corners as well.

1/4" /side is a metric sh1t-ton of toe in.

1/4" is a good way to wear out your tires.

1/8" or less is the norm.

A little toe on a rear wheel drive is ok. It will naturally toe out on acceleration.

That's backwards. It will toe-in more under acceleration. It can be good to have some static toe-in because it will pull towards toe-out under hard braking and if it toes-out enough it will make the car squirrely under hard braking. The better fix for that is stiffer bushings.

Now at 1/8 total. Much better feel.

Different cars will react differently to toe settings. In most cases, toe in will help make the rear more stable, and toe out will help make a car rotate. I run .5° total rear toe (no idea the inch measurement) on my S2000 to help keep the rear in check. Factory toe settings make it incredibly tail happy.
