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 front 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.

More info & photos - Caprice Forum

Photos below show couple of Camaro 345 Brembo (4-piston) calipers with 2 different paint schemes - also available in a Cadillac CTS version, with yet another paint job. These calipers can use either D1001 or D1474A pads, from CTS-V/G8 GXP or SS sedan. Both photos show D1474A pads--with D1001 pad, top surface of caliper is flush for wheel clearance on 18" wheels.
