2009 G37s with sport package
 

Want to change my brakes from OEM to slotted but am confused on the actual size. I am not sure of the rotor sizes. I am in Canada, central Alberta, and yes, it's trying to snow. So if possible I'd prefer to not have to go out and remove the rotors to measure them if possible. Found a few packages at RockAuto, don't want to order the wrong set

Can you discern if the front calipers are four-piston painted alumin(i)um or rusty, crusty unpainted single piston steel? The AWD Sports package has the low-end single piston calipers. RWD Sports has Akebono big brakes. With that info, you can search the board for the correct size rotor. I think it's 330 mm front, 310 mm rear for the Akebonos.

I would only use rockauto for centrix blanks. If you want slotted/cross drilled I would look elsewhere for stoptechs, dba, etc

OP, is your Sport a coupe, sedan, AWD or RWD?

Akebonos on RWD Sport Coupe, RWD Sport Sedan and Sport AWD coupe have 355mm front 350mm rear rotors, AWD and RWD non-sport coupes have 330mm F 330mmR rotors, non sport RWD & AWD sedans have 320mmF 307mmR rotors. And the G37 AWD non-sport coupe went from the small base sedan rotors to 330/330 setup starting in 2010.

Rockauto also carries Stoptech Slotted and Slotted drilled and are a good Canada option

Damn, they didn't have this back when I got mine.:mad:

you're right, they've really increased their product lines the last couple years and are getting harder and harder to beat their prices.
