PPV front brakes - 2011 to 2017 all the same:
- Rotor is 345mm x 30mm

- Caliper is single-piston floating design, uses a high-performance pad with Ferodo HP1000 friction material--same material spec as used on Brembo brakes found on G8 GXP & Chevy SS sedan.

Pad is FMSI D1404 spec.

Standard G8 rotor is 321mm--a good upgrade for G8 is fitting the full PPV setup, or using the PPV 345 rotors with Brembo calipers from 2016/newer Camaro SS or CTS (calipers for 345mm rotors, direct bolt-on to sedans). For G8, caliper mount bolts require opening 12mm holes in knuckles/spindles to 14mm.

Full details - the key to any brake upgrade is a larger rotor, regardless of caliper design or number of pistons.
Rock auto is doing a mislead. See pic.

I really want brembos in the future, but this is just maximizing stock system for now within budget
