The car steering geometry specs will have been designed to make your car

The specs are almost always a *range* so there's room to be at one end or
the other, isn't there?

To make any significant difference to your particular issue, you would
possibly need to go beyond that range.

Have a look at SAI (Steering Axis Inclination) as well. SAI and caster
angles usually increases the positive camber angle of the inside tire
and decreases positive camber angle of the outside tire during a turn
though this will depend on the steering system employed. This is a
designed in effect that you can easily and inadvertently affect when
playing around with other angles.

Unless you have a really good understanding of steering geometry, you
are playing around in the dark.
Like I said, we have no idea what year her 'runner is, and what tires
she is using so we are all, to some extent, "shooting in the dark"
The KPI and SAI are EXTREMELY UNLIKELY to be the problem - that front
end is one of the toughest in the industry. If we know what year it
is, and exactly what tires are on it, we (those who know these things)
can tell her for sure what she needs to address.
