Default Track Day Toe Adjustments

As I begin tuning my track alignment, I need to know how much a full turn on the front and rear tie rods adjusts toe? I suppose I can measure the pitch of the threads on the tie rods, but asking here is easier.

Just make a TOE Bar and use a tape measure.
Just made one today for my C5 , but I use them all the time on real race cars.
I just move 1 side so I can always go back to where I started.

I made mine 75" long with 12" uprights.
I used 12' uprights because thats 1/2 the diameter of the wheel.
Basically a long u-shaped piece.

You place one upright against the side of the tire in the middle of the outside sidewall and measure the distance from the other outside sidewall to the upright .
Stay away from the raised letters. They will affect your measurement.

If the front measurement is larger , it's toed in.

If the rear measurement is larger , it's toed out.

I can't post a pic or I would.
I'm sure someone else on the forum has used this method.

1 turn is around 1/8" to 3/16" at the tire tread on the front, and the rear should be very similar (it is the same basic knuckle).

I leave the rear toed in all the time (wears tires a little though) and set the front to zero for the street, then add 1/2 to one turn out in front. 1/2 turn for long fast tracks, 1 turn only if it is tighter (it will make the car 'darty')

Toe out on the rear makes the car VERY loose.
Loose = hit the wall the rear
tight = you hit the wall with the front
