What is the best settings for wheel alignment. Factory says, Front Toe at Zero. Rear Toe at +2mm. Mine was really responsive before an alignment shop changed it. I think it was at Front Toe Zero, Rear Toe -2mm. Now they have set it to Front Toe +4 and Rear Toe +4, which makes it drive like a big pig. Unless I am confused, + means toe in, and - means toe out.

 

ouch, that much toe in all the way around will really make the car dull. toe in adds straight line stability..

I like to run a tad bit of toe out up front, like 1/16 inch, and just a tad toe in at the rear - about 1/32 to 1/16". more toe out up front makes for quicker turn in, at the expense of straight line stability. and lots of auto x guys tend to run toe OUT in the rear, which helps make the car rotate. depending on how your suspension is setup, this can also make the car very loose, so if you want to start running more aggressive setups, start small and work your way up.

and once you start getting more agressive than 1/16" in toe changes, tire wear will be more noticable, so keep that in mind.

This is close to what I run: 0.50* out in the front, 0* in the rear. Turns in like a Radio Flyer wagon, but still tracks straight on the highway. I don't have the values in inches or mm, as I use the alignment rack at work, but a little math will give you the equivalent.

 

Thanks for the input. Tire diameter is 22.75", so the sine of 0.5 degree X 22.75 = 0.198" or 5mm. That seems like a lot for the road, but might be great for autocross? Any comments?

 

Ah, looking at my alignment sheet again, it's at 0.40* out on each side. With my tires of 22.677" diameter, that gives just over 4mm. I know it sounds like a lot, but even on my little CRX with 7" wide wheels, it doesn't wander around or follow lines in the road. Any movement of the wheel moves the car, so beware of a sneeze on the highway. I love it though, it feels like the car is connected to your brain. I drive it every day, and have driven it thousands of miles on long trips with no problems. Even on the track at 120mph, it feels smoother than at 80mph, so I have no complaints.
