If the tires are non-directional (like MXX3s) you could try swapping the right side wheels & tires for the left side and see if it tracks the other way. XGT-Z and Pilot Sports would have to be dismounted and swapped straight across the car. Be sure to check tread depth across the face of the tires to see if you have significant taper wear. The fix for that is shaving or swapping right-for-left.
If the front alignment checks OK, then be sure to check the rear _caster_ setting (MUST be done with the Viper Service Tools) to see if you have a difference from side-to-side. That will cause the car to lead. Make sure the suspension pivot bushings haven't taken a set. This can lead to uneven ride heights which throws your bump steer curves off.
