youre right I have the solid diff mounts installed and there is no noise or vibration. i will be replacing the subframe mounts soon to the delrin mounts

Not challenging your expertise but I have ridden in both stock 335 bushings, M3 bushing and solid delrin i am speaking from my experience..perhaps the factory setups you speak of are different as I only experienced aftermarket
