UCA decisions
Poly bushings only squeak if they’re improperly installed or improperly lubricated. Poly isn’t rubber, it doesn’t work the same way, and it must be lubricated. Properly lubricated poly bushings do not squeak. That’s why poly bushings should be installed with a grease fitting so they can be greased periodically like other joints that require lubrication, no different than a ball joint or tie rod end. Now, on a convertible without additional chassis reinforcement they may cause other things to squeak and rattle, but that’s a different issue.
As @autoxcuda already alluded to, an idea of your actual alignment numbers would help greatly. Because the car is lowered some settings may not be achievable without offset bushings. But it depends on which settings are out. It also depends on what settings your shop is using, because the factory settings should not be used with radial tires. SKOSH chart, not the factory settings, should be used with radials.
