I thought that I measure twice front and back of the wheel, after a half wheel turn again. Then I'll take the middle value. To compensate for side impact (lurching) of the rim.

It used to be said "win on sunday, sell on monday" racing was ingenious years ago.

In my travels around the garage areas I spied a simple alignment tool consisting of a couple pieces of tubing and some string. By attaching to the car you can lift the car, make a change and then settle it and measure again.

Hello everybody.



Setting the track does not work properly. The rims wheels both have a bit of side impact. Not much, but still I can not set exactly enough with the built gage described above.

Does anyone know "Trakrite"? That actually reads logically. But only works if I drive 100 % straight over the plate. And I'm afraid that there too fast 1/10 "can be wrong ....



Does anyone have experience with it?

Werner, if you fix a tool such as the one I described, or a Duby Gauge or one made from a shower curtain rail between the tyres at the correct height and then roll the car forward without moving the tool from the tyres, any bend or wobble in either wheel remains the same and does not affect the toe in measurement. You leave the tool held between the tyres by the spring and points on its ends and as you roll the car forward it moves downwards then backwards and upwards to just below the wishbone. This is where you look to see how much the tubes have extended (got longer)explanation and this distance is your toe in. There is no averaging or calculation. Just the gap between the marks you make where the tubes meet in front and then behind the axle.

This is the method I was taught in Automotive school years ago. And very nice setup, by the way. It is very accurate. Having said that, the guage between the tires is as well, as long as the guage isn't moved. The distance realitive to the other wheel is the key..

Only now I have understood that correctly! I'll report if I did it right.



Thanks twice, SAJ!
