I have a 2012 g37 Sedan and it's time to get new rotors and breaks. What rotors would you recommend?
Quiet is the most important quality I'm looking for.
I also only plan on having the car for another 20k miles so I don't want to get anything expensive. OEM like would be fine.
After some researching I was thinking this one or this one maybe this one I would like to stay under $100 per rotor.
EDIT: found a brembo rotor for a decent price here on ebay. I just don't know what brand is best.

 

You can get R1 Concept rotors and download Honey it is a google chrome extension and it will find coupons and it comes out really cheap. I have slotted rotors for 20k miles and have no issue. Or you can get the fan-favorite Centric rotors. Also for the pads, I would recommend the Akebono performance pads, they are really great stuff especially as a daily driver.

 

I got my rotors, pads, etc off Rock Auto for a good price. They also sell the ones that have black painted hats on them so they look much more clean behind the wheel

 

Can you confirm if Im ordering the correct rotor from rock auto
I have a 2012 g37 4-door sedan journey.
My current pad sizes are: 320mm Front & 307mm rear

I want to order this:
CENTRIC 32042080 GCX Elemental Protection; Partial Coating Info
Front; Sedan; Base Model; Journey; X Model; X Sport; 320mm Front Disc & 307mm Rear Disc; Dual Piston Front Calipers

I came to the conclusion to get this one because in the description it says "320mm Front"
Does the outside diameter of the rotor have to meet my brake pad size exactly?
I'm seeing big variations in the Outside Diameter. Some are 354.5mm and some are 319.5mm im not sure which one to get.
Here is the page if you can help me pick a good set out.

I would get the ones from Rock Auto that have the black hats on them. Looks much nicer behind the wheel and will hold off rust much longer

Unsure about being perfect. Turns out that I have a small inner rust ring starting that isn't covered by the pad....take that as you will

 

Those rotors would fit your car. This is what I found when looking for Centric rotors for my G...

Sedan = 320mm front 307mm rear
Convertible = 330mm front & rear - I think coupe too? Rockauto says 330mm is Coupe & Centric's website says 330m is convertible so it'd make sense since they're the same body.
IPL or any with Akebono bbk = 355mm front 350mm rear

Manufacturers sometimes have small variations in the sizes they label their pads & rotors. If you're worried about fitment being 100% perfect.. Try & get rotors\pads from the same manufacturer, as opposed to rotors from one & pads from another. Centric is good tho, had them on my last G.

 

I can recommend these if they make them for your car. https://www.napaonline.com/en/p/NB_4...pressionRank=3. Got these back in June and they haven't warped even though I drive HARD, they grip well, and they don't have a spec of rust and still look shiny.
