Yes you can do them. A .5” tall upper ball joint won’t cause any bind in the factory arms. They don’t completely correct the negative camber gain issue, but they do help.

These don’t really cure what you’re after however. They will help with lateral grip, but it’s positive caster you need to help with higher speed stability. The factory arms just don’t allow for much caster adjustment.

“Better handling” needs definition. What does the car need to do better? Faster turn in? More lateral grip? Change in handling balance (push vs loose)?

The tall ball joints make the camber curve a bit more favorable. This will allow the front tires more grip at the limit. Considering the type of tires you’re using, anything you can do to provide mechanical grip through the suspension is going to help.

You’re going to feel the difference when you’re diving into a corner (like rushing a street light that’s about to turn).

Have an alignment done on the car and shoot for as much positive camber that the tech can get. This could be as little as 1* and as much as 3* positive. Each car is going to be a bit different. Dial in -.5* camber and set toe at zero. Don’t bother with a road crown alignment.

Combine with a good shock like the koni classic or Bilstien hd and thats about as good as the car is going to get using factory parts.

Next steps start getting more expensive, more invasive and more compromised towards a specific goal.
