I found shims for the rear pad shape since it's shared among different manufacturers but nothing for the fronts.
So I am in talks with a company that will make a batch of 5 sets so I need 5 buyers to get it done.
Is anyone interested? The titanium shims should drstically reduce heat transfer between the pad and the piston. Seems like a no brainer.
I believe the rears go for $80 to give a ballpark. Not sure about the fronts, still waiting on an email.
Edit: This is for the 2NH "big" brakes (M2C,M5,X5M) and I think they also fit the CCB M4 calipers..
