Front toe-out?
How much toe-out on the front do you think is too much? Also, being mathematically challenged (I still count on my fingers), how many degrees (.10) equals how many inches (1/16)?

1/16" toe out is about .075 degrees each tire (.15 degree total).
degrees toe = inverse sin(toe out in inches/tire diameter in inches) |
We set ours at .15 total toe out in the front and .04 toe out rear (with as little neg camber as possible)

Per,
Is that total toe or per side? I had mine checked last week and RF was -.22 and LF-.19; total toe -.41!! TomA |

I typically don't run a lot of toe on the front and with so little rear camber, I don't need that much in the rear to make the car rotate.
See you in Ft. Myers. |

See you in Ft. Myers. Nice write up in the new GRM on the MINI set up. I found about the same settings after about 2 1/2 seasons screwing with it. I then added camber plates and started over. Funny thing is, I ended up back to the same settings again. Go figure. My MINI just likes them, I guess. Good Luck this season. I'll see you if you come through Peru. I'm one of the slower STX guys, but having fun anyway. ...Mark |
Stupid question - I run a 17" wheel on the street, but I AX with 16's. If I were to get the alignment with my 17's on, would it change the settings when I run the 16's?

As long as the diameter of the tire is approximately the same...

Say I have two wheels- One for street use 17x7 with 215/45-17 outer tire diameter 24.6" and one for autocross 15x7" rim 205/50-15 tire with outer tire diameter 22.9" If I align with 15" wheel on then that is fine for autocross but what happens to the alignment when I change to street tires? Or what if I align with the 17" wheels on then go to autocross and run the 15" wheels? What happens to alignment in the reverse? ??????????????? Anyone have trouble with 1/8" toe out instead of 1/16" out? |
oh, that's just a math porblem, I can usually do those
if you set the toe to 1/16" out with the 15" wheels on, then the toe out with the 17" wheels on would be about 1/15" out, just ever so slightly larger (less than 1/64" different). you can do this yourself for various wheel outer diameters new toe =~ old toe (new wheel diameter / old wheel diameter) =~ 1/16 * (24.6 / 22.9) in this specific case. this is simplified for small angles, but who wants more than 5 degrees of toe? basically, if your wheel diameters change by 5%, your toes settings will change by 5%. |
