what do you track fiends run ?? toe in or toe out? i remember someone telling me 1degree toe in either side will give good steering response and turn-in? is that so

It's toe-out. \ /

 

In autocross, some people set 0.25 inches (6.35mm or .635cm) toe out for each front wheel and 0 in. (0 mm) toe out for each rear wheel.

 

I had my car set at the max toe-out settings and still be with-in the factory specs.

watch out though, too much toe-out will make your car go all over the place at higher speeds (i.e. at the track)--right? I thought for the track you wanted a little toe-in at the front, and close to 0 at the back...I've only read though, so I could be wrong...

 

Am I correct in thinking that too much toe out will make your car dance on the straights though?

 

Out up front. Better turn in. Plus with FWD, under power the fronts will tend to toe in a bit. A little toe out in the front counter acts this effect. As some people have said, too much toe out up front will make the car a darty at high speed.

Not sure about the rear. I run 0. Though I have heard you can dial in more rotation by adjusting rear toe. Not sure which way though.

 

well depends on the track
at the glen i run straight toe for the long straights
and a very slight toe in in the back to ease up on oversteer
and on short courses a slight toe out
but toe out also will wreck tires faster
and camber is another story

 

For a novice (like me) the spec settings are probably good & safe for high speed track days, neutral in front and a little toe-in in the rear. Toe out will make the car more dodgy at speed, especially in the rear. A guy we autoX with has a modded CRX in CSP, he's got like 2 degrees toe out on all four wheels...it's funny watching him on the highway, it's like a ball bearing in a pinball machine. Not the best for stability, great for lower-speed cornering. Toe out in the rear if you want the tail to come around eagerly.

 

Sounds like some of you who tried different toe settings don't really know what toe-in and toe-out are for?

N1 Spec, it depends on your driving style. You like understeer? Oversteer? Let me know and I'll try to help.

 

yes i admit i know how to drive but i really need to sharpen up my knowledge on sussy setup.

Wai: i like neutral-moderate oversteer..... the reason i posted this topic was becos i rememeber reading or someone telling me that toe-in at the front give you good steering response, and i also read somewhere on this board saying otherwise. Im getting my wheel alligned tomorrow with my new Azenis tyres and a trackday is coming up real soon.

 

I always thought toe out would increase turn in, while being more unstable.

oh well, i run toe out all around. Car rotates like no tomorrow.

A 1/16" total toe out for the front is a good start for track use and 0 in the rear is safe. If you start adding toe out to the rear you better know how to use the throttle to pull the car out of an oversteering condition. For autox you can try 1/8" to 3/16" toe out up front and if you need to help the rear add a tad of toe out in the rear. Remember that screwed up toe settings will eat tires a hell of a lot faster than too much camber. Also the more toe out or for that matter toe in you have the more you'll effect top end speed since you have to "scrub" the tires going down the straight away. Don't forget about adding caster if you can.

 

Hi N1-Spec, everyone starts from zero knowledge and learns gradually. I'm glad that you asked instead of spending the time to do trial and error. Honestly I just knew the purpose of toe settings not too long ago either.

Toe settings give most effect to the tire that is loaded. Let's picture the scenario:

When you brake into a right turn, your left front tire would be most loaded. If you have front toe-out, the loaded tire would be pointing slightly towards the outside of the turn -- thus a slight plow into a turn.

When you exit out of this same corner with full throttle, the left rear tire would be most loaded. If you have rear toe out, the loaded tire would be pointing slightly towards the outside of the turn -- thus a slight on-throttle oversteer out of a turn.

With this setting it should give a neutral-moderate behavior, kind of like an AWD car.

Keep in mind that ANY +/- camber or toe in/out would cost you tire life and the car's performance in a straight line (increase braking distance, loss of stability, etc.) But they're considered as good trade-offs.

Hope that helps. Have fun and be safe at the track!

 

I run slight toe-out on my R compounds but on street tires I like the feel of toe-in.
