I just replaced the rear pads on my '18 MCS with Carbotech XP8. The outboard pad would fit with the factory pad clips installed, the inboard pad would slide in on the lower tab, the top tab would not. I didn't want to force the pad so i removed the clips altogether. They rattle quite a bit on normal roads when I did a run to bed the pads in. This car is used mostly on the track with some occassional around town driving. Thoughts on clip/no clips? Thx!
