Park the car on a flat level surface, get out and bounce the suspension front & rear a little to settle it.
Get a tape measure and measure between the floor and the 2 large bolt heads under the very front end of the heater channel. Then measure the other side. If this measurement is out between sides then the car itself is leaning. If it's pretty even then it's either your front wings or your front 1/4's that are out of position. Don't measure to the beam, measure to the body.
Should the car be leaning then you need to prove if it's the front or rear that's causing it so put a trolley jack under the dead centre of the front beam and jack the car (rear wheels chocked) till both front wheels are in the air. Measure from the floor to the rear torsion end caps. This will tell you if it's the rear suspension or the front that's causing the lean.
I had a twisted frame head due to accident damage on my car from a previous owner, but I didn't realise at first so I tweaked the rear torsion bars till the car sat level. Didn't figure out what was really going on till years later. All fixed now. https://www.volkszone.com/VZi/showthread.php?t=375003
I also had a mate's car that had the same problem as yourself, it was aftermarket wings causing it that time. If wings are a problem, trial fit them before painting and keep the receipt till you've got a pair that fit right.
Edit - of course it goes without saying - make sure your tyres are the same make and size side to side and that the tyre pressures are correct before you start - Front and rear !
