mixing brake pad materials
I have done some searching and still on the fence.
GM semi metallic pads up front and ceramic pads ( Posi Quiet ) in the rear.
Should I have any concerns?
The car isn't pushed in braking and street only.
I think I am ok but the mix match has me pondering.
Long story on why the situation came about.

Well I decided to go with the semi metallic in the rear too. AC Delco.
For the street and the way I brake the mix most likely would not be noticeable.
I just feel better being all OEM and staying with the semi metallic pads.
Brake dust has never been a issue with me and I rather have the expected initial pad bite.

This is just an opinion...I think you are OK.
Replaced both rears w/ one type of material compound, keep other type in front.
Brake bias/ stopping power front to rear affected.
Heat differences front rotors to rear rotors I don't think matter.
Active handling may feel different.
ABS stopping distance may be different.
Both these you can test and adapt.
Again, seems like this is OK.
Good luck.

My take on it, Dave, is I'm glad you changed the rears to match the front pads' compound. I'm sure under "regular" driving, things would be fine the way you had it. But, "regular" driving also includes panic stops and situations where you could be braking in a curve, or swerving and braking hard at the same time.
That would be a bad time to find out the difference in pad compound doesn't work well together. It's a completely different story, of course, if you can test it all out under safe and controlled conditions to determine if they work well together.
