Im going with AKG red 75d subframe bushings but Im debating if I should replace the differential bushings as well or just install a diff brace. Reason why Im hesitant to go solid's is I don't want NVH, maybe theres polys out there that dont cause noise? Im around 650whp so want the rear end to me more firm.

I have akg blacks with LSD and no brace, but I can't give much feedback since my car is never running and I have runflats on 19's.
