Question toe adjustment for best performance

well we're not talking about our foot toe here.

i've serached the web for an answer to this toe thing and came up with all i think that said toe out for oversteer.

since GT2 is the only thing i can get to that simulates real-life situations, i've done some experiments.

this is front toe settings:
my findings were that toe-out gave more response to turn in but when the weight transfered, the car didn't turn as much.

with toe-in the car turn a bit not as responsive but throughout the turn it turned well and even on exit it kept turning due to weight transfer.

so what should be the correct or recommended toe for"

*street/weekend racing
on a real car.

correct me on any mistakes here ok
this thread is not off-topic. please don't move this thread because it says GT2 on it. it was the only thing i can get to that siimulates real-life situations.

I know of M3 SCCA racers who experimented with slight toe-out and toe-in on the front, and 0 toe in front was always faster after numerous track laps of experimentation.

Now this is for the M3, so it has no bearing on a toe settings for a Subaru. I have yet to align and race my rex.

0 toe at rest will usually mean a slight bit of toe out once your moving.

also keep in mind, toe out will cause you car to no longer be stable in a straight line. It will want to wander and twitch, so ya gotta keep your hands on the wheel!

A friend of mine just had auto-x alignment done on his 2.5RS after asking me what settings to use.
The shop gave him -0.1 degrees front toe out on each side, or -0.2 degrees total, along with -1.0 degrees front camber. He is running on Kumho 712's on stock rims.

The car is much grippier in the front now, mainly due to the negative camber. However he has remarked to me that turn in is MUCH improved. I have yet to get a chance behind the wheel of his car, but I'm sure I will soon and I'll let you know what I think of his setup.

It's Blue, ok?


Toe out on the rear of the car will help in the cars rotation ( the outside rear tire is helping to guide the car through the drift.

Toe out on the front of the car will help in the initial turn in, or to quote Sir Jack Bravam (I think it was it was him) "To present the car to the corner"

A combination of both will lead to evil handling on the street as your tires will track on every groove, bump, crack, or imperfection on the pavement

Don't know what the effects would be on a rally suspension, except that I imagine that it the effects would be more dramatic for the same adjustment when compared to an autoX alignment.

If your really curious, buy this book "tune to win" and "drive to win" by Carrol Smith. This will introduce you to the dynamics of car setup, plus driving techniques used by professional drivers. It's good reading on a snowy day
