Correct me if I am wrong but the front brakes on the S coupe are four piston (dual opposed) and have larger rotors than the sedan? I unsure of the rear specs... Has anyone installed these brake components from the S coupe onto the S sedan?

Cheers

 

All sport models have the same brakes - both coupe and sedan. Same parts. Front and rear.

 

Z34/ G sedan Sport/G coupe Sport all use the same Akebono calipers and larger rotor.

 

Hhmmm... I have a 2009 XS and my brakes do not look like this:

 

Yeah, the AWD S sedans got shortchanged on the brakes, the AWD S coupes have those nice big Akebonos. Here's a thread that will show everything you'll need to do the switch, luckily your wheels will clear those brakes, so that's one less expense to deal with.

Awesome! Thank-you.
