Driver In/Out illustrates an interesting point in karting.
Yes, it does make a significant difference whether the driver is in/out.
If you only measure it with the driver OUT, then how do you KNOW if it's the 'perfect setting' or not? If you TEST all the 'toe in/out' settings against lap times, you CAN find out the 'ideal' for the conditions that prevailed on THAT test.... without that.... all you can do is set your 'toe in/out' to the 'manufacturers settings'..... but of course, that relies on the manufacturer TESTING your current kart with YOUR weight distribution and conditions..... which they are VERY unlikely to have done.....
The point I am trying to make is that you see drivers/mechanics setting all manner of 'values' to utterly PRECISE 'numbers' (i.e., 1.2mm toe out) without EVER checking if it works better with 1.2mm or 1.1mm or 1.3mm. At best, they MAY have tested at 1mm, 2mm and 3mm and thus they have ZERO knowledge of the effect of 0.2mm on the handling....
My point is simple.... only 'set up' to an accuracy level about which ANYONE can have knowledge of the effect of being 'innacurate' to taht degree.
Put crudely, you are WASTING YOUR TIME measuring toe-in/out to 0.01mms accuracy if you do not KNOW that such accuracy makes a difference to YOUR chassis!
We KNOW the effect on 0.1mm accuracy on a piston size. We KNOW the effect on wheel bearings if they are 0.1mm out of shape.... we DON'T know the effect of being 0.1mm innacurate on toe-in/out and thus it's a JOKE to worry about it!
The same is true for LOADS of measurements you see being taken on a kart. Ask yourself HONESTLY about each of them. Do you KNOW the difference in handling between:-
1) 1mm wider rear track-width?
2) 1 degree more caster angle?
3) 1 degree less camber
4) etc., etc..
If you claim to 'know' the difference in any of the above.... then ask yourself HOW do you 'know'.....?
If you 'know' those answers then USE your accurate knowledge..... if you don't.... and that's at LEAST 95% of karters... think about the importance of measuring things to an accuarcy level that you CANNOT know if it matters or not.......
