Please bear with me here as I am newbie for brakes.

So I need new pads and rotors for my 07 g35 coupe 6mt. And I am totally confused as to which ones to get. Can you anyone please tell me which size rotors to get? I tried to measure the current ones (which I don't think are stock) and they 12" for front and 11" for rear. Does this sound about right size? I am worried about ordering rotors online only to find out that my callipers don't fit them. Or does that not matter and calipers would fit even with slight different size rotors?

What is the standard size rotors on this car? And does it have Brembo brakes? The currently installed rotors on my car are not really bad but they are drilled and slotted and it seems that no one knows how to machine them. So I guess I need to replace them all.

I am also attaching pictures of my current rotors (in case it helps anyone in identifying them).

Thanks!

Those arent brembos and you would be fine just getting the same size rotors you have on there now. Are they that warped you need to replace all of them or just the front?

If they are not warped -> Pads only

If they are warped -> New Pads & Rotors

Recommendations for Street Use:

OEM pads if you don't mind dust.
Akebono Pro ACT if you don't want dust

Blank "Premium" Rotors (ie not house brands like Duralast, go for Raybestos or ACDelco).
DBA 4000 series for slotted/drilled.

Brake rotors are all about mass. The heavier they are, the longer they take to heat up, and the less likely they will 'warp'.

I think only the front rotors are somewhat warped because they vibrate at high speed braking. The rear ones seems fine. I just talked to a guy in Oreilly's and he said that they can machine my rotors. So it seems like I only need to get the front rotors machines/turned and new pads all around.

Does it make a difference if I use ceramic pads on semi metallic rotors? Or do they have to be of same kind. I think my rotors are semi metallic.

And does it make a difference if the g is sport or not sport in terms of the brakes?

What do you guys think? Is this good?

Alright guys, after countless hours of research I have narrowed down to following options. Money is an issue so I just need something that gives decent braking and reliability:

Akebono ACT905 ProACT:
Bendix D905 CQ Brake:
Raybestos:
I am inclining towards bendix (for the price), has anyone had experience with them or know if it a good choice or not?

I really appreciate any help as I really need to get them ordered today. Thanks!
