Like a lot of us, I also recently did the same thing (with EBC pads, rather than Hawk). I noticed before I ordered that EBC part number info wasn't easy to find or verify, due to Brembo vs non, and different part listings on different websites. So, for future Googlers, here's what I found out for Brembo Calipers (2.0T R-Spec, 3.8 R-Spec, 3.8 Track/Ultimate).
Front Redstuff: DP31210C
(currently, ignore that Amazon falsely reports these will not fit your Brembo car)
Rear Redstuff: DP31140C
(interchangeable with DP31156C
(I was sent a "DP31140C" box with "DP31156C" written on the pad backing plates)
I noticed that some of the EBC part numbers are similar across their Green, Red, Yellow and Blue series.
The DP1210C Redstuff pads fit perfectly in the front calipers, much like you see in the video posted above. In the rear, though, the DP1140C Redstuff (mine were marked on the plates as DP1156C) pads would not slide into the calipers, although they visually matched the OEM Ferodo pads. So, I carefully and gently sanded the caliper-guided edges of these rear pads down using a belt sander. You could also sand by hand in a pinch, or use a rasp or grinder, etc. You may only need to shave less than 1mm off each side, most of which is the paint coating. I took care to slightly bevel the ground edges to remove any burs.
I used a small amount of the EBC lube on the pins, backing plates, and in the case of the rears due to the sanding, on the sliding edges of the rear pads, but not before cleaning each corner's components thoroughly. I used Armour All's Extreme Wheel & Tire Cleaner, which is safe for the Brembo paint and does a fantastic job lifting all the hidden dust and grease from parts. After a few minutes I rinsed and then I then coated everything (except rotor pad surfaces) liberally with Armour All Tire Foam. A detailing trick, tire foam makes everything look new, basically, coating with a petroleum-based residue which lasts for a good while, depending on rain driving.
So, I'm impressed with the EBC Redstuff ceramic pads over the metallic and incredibly dusty Ferodo pads used in the OEM Brembos. I hope this info supplements the video and helps anyone who may be looking to order EBC.
