Angel Pads are awesome! I use it when I autocross the 535. The BMW Comfort seats don't hold me in place when driving aggressively. I used to wedge my left knee against the door to keep from sliding. Not ideal. The Angel Pads keep my sides braced and my butt from sliding on the leather. No more bruises on my knee and my leg stays away from the door. Thanks!
