I can offer this:
I bought Akebono pads through RockAuto. They sell TWO DIFFERENT Akebono products, so be careful!!
The ProACT ceramic are categorized for "Daily Driver". I did not buy these.
The ASP Performance ceramic are categorized as "High Performance. I bought these.
My (2021 Canadian TRD Off Road) 4Runner came with OEM Advics pads directly from Tahara, Japan, with Friction Code FG.
Th ASP Performance (ASP606A rear, ASP976 front) were labelled with Friction Code GG.
My early driving does give me the expected (and desired) better Cold Bite (250-degree and lower). Less of the stock spongy feeling too, which wasn't expected. And since the Hot 'G' is the same, I expect all 650-degree and hotter braking to be the same.
So, in the first few minutes, I'm a happy camper. The Akebono ASP performance ceramic pads are giving me exactly what I wanted.
(Other data for later Googlers:
- my rear brake pads wore faster than the front pads
- in 50,000km I had only 2mm remaining on rear pads ... clearly time to change!)
- I drove these 50,000km in 3 years, much of it city-driving)
