PowerFlex upper RSM (rear shock mount) replace the upper mount bushings and washers (items 6 and 7, washers are shown integral to 6 and 7). I’d recommend the street performance (yellow) version which is not significantly stiffer than stock and are a good match with the improved performance of the Evolve/Bilstein B6 Damptronic sport dampers. I’m using the yellow on my ‘12 e92 M3 with JRZ RS1 dampers with 350/620 lbf/in.

Can you provide a powerflex part number for that? having trouble locating it.
