I would tend to agree with this statement.
A Kart uses a SOLID rear axle... this requires that the chassis flexs enough
to allow the rear inside wheel to lift (leave the ground) so as to allow it
to turn more rapidly, since the outside wheel has to turn more times than
the inside wheel to make a corner. Without the chassis flexing enough to
let the inside wheel (lift) turn faster.... your turning radius is going to
grow. It will feel like serious understeer.

My 2 cents
