[M3NickM3]

Anyone else have this? Usually after M mode has been engaged, I can feel a vibration rumbling from feet to knees in driver foot well, nothing major, I’m pretty sure I may have had this in my E92s and W204, but my M2 has the same engine and wasn’t restricted by much and never had this rumbling.

Under the bonnet engine shakes a bit, not knocking but definitely shakes.

It feels normal as it’s a sports car, but also gives me a concern
