First time I've seen a change in toe quantified, Car and Driver 1st gen Insight test.
 

from
2000 Honda Insight - Long-Term Road Test - Auto Reviews - Car and Driver

Almost a 7.5% drop in setting from zero toe to 1/8" toe in just the front. Inversely it would provide a gain of 8.5%. Huge!

I can't say how thorough their testing was to get those numbers, but it shows promise.

Honda CRX also calls for zero toe-in +- .08 inch.

How uncommon is zero toe-in?

I can attest to Insight twitchy, but mostly on grooved pavement.

Most all cars that are not on the extreme end for fuel economy have toe in.

Interesting read, though I think their driving is majorly at fault. With mine (bought used with 50K miles) I'm at 71 mpg average over 6 years/85K miles - much of that driving in/over the Sierra Nevada, too.

I was, however, amused by one almost prescient comment: "Don't even think about dialing a cell phone while driving this car."

Zero toe is a common mod for EV'ers. I guess they figure that they go slow enough that any extra twitchiness wouldn't affect them too much.

The less toe, the better the efficiency? Nature already knows this: Many members of the Vadoma tribe in Zimbabwe are born with only two toes and supposedly can walk great distances without tiring.

...an excellent "rule-of-thumb" pair of numbers to know about!

...this info aught to be captured permanently (sticky?)

Has anyone tried this

Starting with a stock car and modified the toe of their wheels to be 0.
I would like to knoe if anyone has good results for this mod. I have changed my power steering rack which affects the toe of the wheels so my car isn't stock so i cant see the before and after of this mod.

I am interested in putting this mod into the mod wiki list but i might not bother if nobody has tried it and gotten favourable results.

Heck of a post rez but glad to see it as I missed it first time around.

I also am wondering about what improvements there would be.
I have a new set of tires that I need put on in a few weeks and was debating about an alignment anyway.

Anyone know how to find out what the factory toe and camber settings on a car would be?

Try your owners manual spec section .

Honda Accord also has toe =0, camber =0 for front .

I can tell ya from past experience if you adjust an older car with stock 1/8 toe in to 0 it will feel touchy, when driving straight, no crown affects (not a good feel overall ) .
