it’s a metal to metal connection. To some amount there will be more NVH (noise, vibration, harshness).
not a good idea in a Cadillac.
but are you adding sway bars, bigger torsion bars, and other handling improvements? Is this a high performance car with headers, cam, etc... basically it makes more noise than a 318-2bbl ?? If so, I doubt you’d hear or feel much difference.
everyone’s sensitivity and expectations are slightly different. So tough to predict your perception.
I ran poly strut bushing for 17 years. But I cut and shaved the rear bushing 3/8” and the center sleeve. I got 3-4 degrees caster with moog 7103 offset UCA rubber bushings.
