BBK Part Sourcing
I'm putting a BBK together. I'm trying to decide if I should go with the 12.6" rotors (from 04+ Maximas, right?) or the 13" Cobra rotors (which years are used for these?). I'm not sure where most people tend to get their rotors from or how much each one is.
So those who have a BBK using the Z32 caliper, which rotor did you go with and why?

I think the 5th gen rotors are a good call since they are only .4" difference. The 5th gen rotors can be found for cheaper and will work just as good with some double piston calipers or even the 5th gen calipers. Thats what I've read up on at least and I will be doing in the future.

im thinkin if your autoXing.. or have the money to blow then go with the 13in cobra and 300z calipers.. i mean no matter how u look at it ur gonna need bigger wheels... brake bias is gonan be an issue most likely..
personally id go with and i am goin with 13in cobra rotor and q45 calipers...
i found rotors cheaper all over but automax seems to be the only one who can redrill them to maxima spec or w/e that is.. cobra rotor years are like late 90's im pretty sure..good luck and let us know how u make out w everything

I think you mean 6th gen, right? I think rotors from 89 all the way to 03 are the same. Not until 04 do they get any larger, specifically 12.6".

i chose the 6th gen rotors mainly because u dont need the hubcentric rings....and fit perfectly.....the .4 of an inch difference hasnt shown to hurt me on roadcourses or auto-x......plus i got matts brackets on sale and they came with covnersion lines...less part sourcing...i got my rotors from rockauto.com they are Raybestos rotors and i havent had any issues with them.....04/05

yea, i would think that once you upgrade to the 4 piston calipers and the significantly larger rotor, either setup shows huge improvements over stock. and yea, the cobras require redrilling for the studs and the hubcentric ring.
so matt makes the brackets for the 6th gen rotors and jeff for the cobras?

IMHO from what I've read. 4 piston calipers if the total piston area is larger than OEM than yes, it will increase breaking force. But it's mainly for braking feel and fade resistance.
Most of the increased braking force is from moving the caliper out and thus increasing the torque arm force. So in theory a caliper moved out to accomodate a 13" rotor should be able to have more torque arm force than a caliper accomodated for a 12.6". But both are much better than stock and the diff inbetween a 13" and 12.6" is not nearly as large as the move up from the stockish 11.x" stocker.

like Jeff said, stock 4th gen rotors are ~11" while the 6th gens are 12.6" i don't see how you can get around that without a bracket to move the caliper out.

There are alot of brake kits out for the maxima. You guys need to really read closer.
If you use the 6th gen rotors AND CALIPERS, it's bolt up(aside from the drilling of the bolt holes). 6-gen calipers are huge one piston jobs though. Using the Q/J or 300z calipers, the a bracket is necessary

So I was right. I plan on using all striaght 6th gen parts. You think it's more worth it to upgrade to bigger calipers? I dont autox or anything. Just want a little better stopping power for a fairly cheap price...Jeff you know all about this stuff. Help me out.

I think it's great cost effective upgrade. You should be happy with it. If not, you can always sell and upgrade again.
