Thread: B13 brake upgrade aficionados

Okay guys, I'm going for the completion of my brake upgrade and I have a few quick questions that I couldnt find searching on either of the forums. I already have the AD22Vs on the front and am going for the Maximas on the rear.

1. Does it matter what Altima MC I use (SE with the rear discs or any other trim, I already know to match the OE brand)

2. Is it worth having the Maxima rotors re-drilled or should I attempt to find Euro NX rotors?

3. Is there any validity to the posts that I have seen that some G20s have the larger rear rotors? (I've seen the statement twice and was like wtf?)

A link to an accurate write-up on the swap would be nice, thanks

anyone at all?

When I did my maxima rears I just got the rotors and master cylinder from Greg V. at G-Spec. He told me what Altima the MC is meant for, but I've forgotten. Also, my rotors were 4 lug, non-converted. I dunno, I just call the guy and he hooks me up.

FYI I have Fastbrake kit up front.

I'm pretty happy with my NX kit, but I could go for an upgrade in the rear as well as the possibility of drilled/slotted in the front.

2. Euro NX rear rotors. They are easy to find.

No drilled rotors. Jesus Christ. Where do you people come from?

LOL what's wrong with drilled?

Thats kind of the last step for me. Like high quality pads first, obviously. I'm pretty sure that I have like the cheapest Napa pads available on there right now.

Drilled holes in brake rotors are for looks only. They allow for quicker cooling of the rotor in some, rare racing situations with proper brake ducts. Other than that, they are for looks. They take away so much material that brake fade comes on quicker. The only way to prevent this is to oversize the rotor (last I checked, Porsche and a few others oversize their drilled rotors, which is a plus for them as it fills out their wheels better, etc.) but we have no room in our small wheels for over sized rotors. They also promote cracking of the rotor as the rotor overheats quicker, and there's nice holes in the rotor already for cracks to start from. Not to mention most companies don't drill their rotors properly, failing to counter sink the holes (or what ever it's called) and drilling through the rotor without making sure the vanes inside aren't messed up or drilled through.

I'm sorry this isn't as technical as I'd like it to be, it's just that I'm frustrated tonight. Every where I turn it seems like there's newb question after newb question, with random shіt like "What? Drilled rotors aren't teh sex?" all over the place on multiple forums I frequent.

WELCOME TO 1996! DRILLED ROTORS ARE FOR LOOKS ONLY!!

Haha sorry, I didn't know it was a noob question

Be as technical as you'd like since I enjoy that side of things much more lol.

What you have said makes sense to me though, as holes do cause a stress concentration and without proper convection through them they would more than likely hurt the heat transfer (as you have mentioned). I guess I never gave it thought and just assumed they did their job. Glad you have pointed that out before I someday made the stupid mistake of buying them.

Slotted rotors on the other hand, while still having stress concentrations, seem like they would actually increase the area for convection transfer as well as provide the necessary air flow. Do they work then?

And by proper material manufacturing and slot design I'm sure they can overcome the problems caused by the stress concentration.

Sorry if this is also a noob Q
