I have 2004 G35 Sedan Standard with Auto transmission. I'm getting to replace my rear brake rotors, and was wondering if anyone know whether the rotors are Single Piston Calipers or Dual Piston Calipers?

Thanks.

'03 and '04 Non-Brembo Coupes
Front: 11.65-inch x 0.94-inch power-assisted vented disc - 1 piston
Rear: 11.5-inch x 0.63-inch power-assisted vented disc - 1 piston

for 2004 im pretty sure its single piston

 

unless you have BREMBO brakes on your 2004 then it is a 1 piston caliper

 

Thanks guys. Almost bought dual piston.
