I also found the stock brakes to be sensitive & "grabby" at slow speeds.
Additionally they threw a lot of brake dust & squealed quite a bit.
I installed a set of HWAK Ceramic brake pads front & rear Part #'s: (Front - HB828Z.760 Rear - HB193Z.670)
All of the issues mentioned above were resolved.
The only caveat is that on the rear pads there is no provision for the wear sensor, which for me wasn't a big deal as I just tied it off to the side.
BTW, These pads are available from AMAZON
Good luck!
