I just ordered up the 2 degree alluminum rear hubs...

Question:

I want 3 degree toe.
Whats the difference of running 2 degree shims with 1 degree hubs vs 1 degree shims with 2 degree hubs. I know the end result is 3 degrees toe but side by side comparison what is the on track difference in feel or handling.. ect ect.

Thanks in advance.

In my experience on carpet with foams:

1d hubs with 2d in-board toe-in (shims)
* Decreases rear traction on entry and mid corner
* Increases rear traction on exit (anywhere on-power)

2d hubs with 1d in-board toe-in (shims)
* Increases rear traction on entry and mid corner
* Decreases rear traction on exit (anywhere on-power)

In the past I've used the 1d hubs (with 0d in-board toe-in), but now I use the 2d hubs (with 1d in-board toe-out for an overall 1d rear toe-in) as it loosens the rear end on-power.

The more out-board toe you have in the hubs, the less the camber changes at the wheels when going from off-power to on-power. It brings more overall rear stability.

Now, the more the rear arms are swept further backward (less in-board toe-in), the more your rear tires will increase in negative camber as the suspension squats under power. This reduces the contact patches of both rear tires, thus reducing overall grip on-power. But since its negative camber gain, the outside loaded rear tire is leaning more into the corner and it gives a very controlled rear end rotation.

I know this is fairly old, but I have a question regarding this.

For rear toe, do you aim for a set amount of toe in, no matter which degree rear hubs you run?

I have 2degree hubs for my 04, but haven't put them on yet (waiting for the car rebuild in a week). Should I just be experimenting with it at first? Start with just the toe given by the hubs and then change it. When doing this, should I be adding or subtracting overall rear toe-in?

Thanks.

In my expereience, using the 2d hubs will stabilize the rear end more off-power and allow for more rotation on-power. This assumes that you are correcting the overall rear toe back to where it was using the suspension holder shims.
