EBC Green - Original and Upgraded???

[hkka]

I check the EBC site and see they have "original quality" and "upgrade quality" for their brake pad.

I got a set of Green pads front for my 172 and it said DP21369 on box. But then, what is the upgrade quality one??? Upgraded one is DP31369 :-(

See here:

If you see the vertical line that shown on many pages, it read: STANDARD Quality - ECE R90 Approved with similar performance to original equipment brake pads. So, where can I get the Upgrade Quality one??? Yellow Stuffs??

The greenstuff pads are the upgraded pad for fast road use . The yellow stuff are really aimed at track use .
