We have installed these at our shop and the increase in harshness is very little, Especially on street compliant suspension and tires.

I heard the GTS has solid subframe bushings (mounts) but have never seen a picture of them. I wonder if they are alloy, delrin or other? They are likely only available from BMW with the complete subframe.

Re the M5, does anyone have pictures of the solid mounts? I should get under a new M5 to see if BMW employed any tricks to tame the NVH when using the solid subframe mounts. Maybe liquid-filled diff mounts

IMO, any E9X M3 that is either driven hard and/or has more power than stock could really benefit from solid subframe mounts. My ESS VT2-625 kit made this issue far more obvious!
