“Toe in” is always bad, never set the toe in, you will regret it immediately.
“Toe out” will give the vehicle more steering stability in the corners. The more “toe”, the more stabile on he corners less “twitchy”.
But, toe scrubs straight away speed, so you must find a balance for your track.
We run the LF 1/16th out in our karts.
We generally generally run 1/8th to 1/16th total toe in our cars, but we have ran as much as 3/16th. But that’s cars.
The problem with ZERO toe if Sid you make wheel contract, you might end up toed in.
