The NA series is blue and the NA-R stopped me fine from 160kph on my first run at the strip at which time they would be cold
GTS-T V SPEC You speak from experience, so do I, how come our experience appears to be so different? I have Endless NA-R on front ,standard Bendix on back. They seem very soft in as much as they bite with very little pressure applied at low speed hot or cold and not much more comeing down from 160. generate a lot of light grey dust but are totally silent, I get the feeling they won't be long lasting though.
