Moneygrab? They are standard and the price of the car is largely the same...

Yup, just did the brakes in my 2016 STI. The dealer wanted about $3ooo using OEM pads and rotors. Ordering the parts online is roughly $1700 from the Subaru online parts stores. (The service manager also offered to let me bring my own rotors and pads and then it was $700 for the labor.
