I know this subject has been beat to death, but as title states, anybody running solid subframe mounts with stock diff bushings? 6MT specifically. Seems like not many are doing this.

My car is heading in for a major overhaul, and while it will see track duty, it also will see street and highway driving. I know even the purple and black powerflex transmit a lot of whine. Wondering who has done just the subframe only, and how it is holding up on track?

I ran this exact setup on me E46 M3 for years on track with no issues, but the E92 does have a lot more power through the drivetrain. Me thinks the solid subframe would help stabilize the diff more, even with OE bushings. Didn't the GTS come with solid sub mounts and stock rubber diff mounts?
