I came across this on the internet

It has me wonder, what is the best for road racing? Do you guys toe in or toe out your cars?? Previously I would have always argued toe out, but now I'm not so sure anymore

 

I like 0 toe on the front of an s2000.

 

i prefer 0 toe front, .22 toe in on the rear

 

I tried a moderately aggressive autocross alignment the last time I did it. I had toe out on the front, toe in on the rears and almost as much camber as I could get. While it drove great, it raped my tires. Next time I'm going 0 on the front and barely toe in on the rears.

 

I post this because I was having a discussion with some friends on which is better for the front, toe in or toe out. He says toe in, while I say toe out. I found that link that even said road racing cars toe in, which is new to me... I was hoping someone could shed some light on this? I had always assumed toe out would give a more aggressive handling?

 

Front toe out can help with turn-in on the track. I have a square set-up and find that it turns in well with zero front toe. My Triumph TR3 needs a little help with turn in, thus it has 1/16 toe out.

 

For road racing, no auto-x...

Aim for 0 toe front.

However, if I had to chose between toe in or toe out, I'd go for a minimal amount of toe in. It stabilizes the chassis.

Toe out up front is useful for some cars. S2000 isn't one of them. Adding any toe out will decrease straight line stability (especially at higher speeds), make the car darty under braking, wander over bumps, and can cause understeer once the chassis takes a set.

 

0 up front and mild-moderate toe in for the rear

 

0 toe at the front and 1/8 to 3/16 total toe in the rear.
