Sorry I didnt reply to your email sooner.
Yes - there are some differences between the camber angles on the racing
kart and off-road kart plans on the kartbuilding website.
It is 5 degrees on the off-road and 12 on the racing kart (
The exact angle depends on the type of wheel/tyre been used. On the
off-road kart which had wheelbarrow wheels, a 5 degree angle sufficed. On
the racing kart, the wheels were substantially wider. There is no
definitive camber angle, or any equation to calculate this angle (as far
as I am aware). I wrote a blog post on steering in karts and it can be
To summarize, as the wheelbarrow wheels on the off-road kart were round
(as opposed to flat), a 5 degree angle sufficed (a larger angle would not
make any difference to tire wear etc.). I suggest you use 10
degrees for the camber angle on your kart. It would be possible to adjust
the camber angle afterwards, although it would require some work.
Best of Luck,
