Anyone know if the Sumitomo 100.08150 and 100.09050 brake pads which Centric distributes are the REAL OEM formulation that Infiniti provided as the revised warranty replacement pads (with blue-colored backing) on the 2003 G35 (Non-Brembo) ?

Or are the Hitachi W0133 series the revised OEM pads?

After three years of weak initial bite on a low dusting organic pad (Centric Posi-Quiet 106) - and a recent afternoon of track hot laps in a new BMW M3 - I am ready to return to the stock G35 brake feel and performance.

I was considering Centric's newly released StopTech 309 street-track pad, but I haven't found much feedback on this or any other forum.

Coincidentally (or not so) the Sumitomos and the Centric Stop Tech 309s are priced nearly the same.

Thanks in advance.
