the KVR pads I had (KVR Carbon Kevlar Brake Pads) wore too fast and unevenly, the inside pads (Z32 4 corner) wore considerably faster than the outside, and didn’t last as long as I would have liked. Other than that they were nice pads, a little short lived, good stopping power, but not as good as hot porterfields
I am pretty sure bing has run those KVR’s aswell and noticed the same thing.
However the porterfields (RS4 fronts) lasted me like 20+ months, and wore evenly (same calipers).
