No real preference in pads, OEM usually works well with OEM parts.
EBC makes... er ...SELLS good rotors, some of the best readily available, better than OEM usually.
EBC knows brakes.
EBC has a 330mm rotor for "old" TZs... COOL, I want some. Canada is serviced by EBC-USA. EBC-USA doesn't stock that part number. EBC-Britain has the part, can't sell it to me, I'm in Canada... round and round we go... I ended up making some.
If you put metal pads on OEM rotors, expect rotor wear (with no real gain). IMO Stick to organic, ceramic lasts longer... doesn't work better, just lasts longer
... the word's SINTERED, which means metal. H is aggressive, HH is VERY aggressive ...BUT at 1/3 the price? They're going on my bike. $20 bucks is $20 bucks... nothing lasts forever
