I get some gear whine from the diff. It's just enough to hear it. Couldn't hear any when I just had the SPL solid diff bushings. I don't hear any new rattles. I can hardly hear the radio. I have FI LTH's, 12" resonators, and FI cans.

If you don't want to drop the sub-frame. The Z1 inserts are the way to go. You most likely get the same feeling with the Z1 inserts and the poly bushings. The poly bushings. If you go through the trouble of dropping the sub-frame. Go with the SPL's. My experience with installing poly diff bushing vs the SPL diff bushing. The SPL's was easier to install. I imagine it's the same with the sub-frame bushings.
