another pic. There is an area of unswept contact on the rotor BEFORE it curves into the hat area. But you knew this right?

Im done...you and i can't debate ever because you always get off subject, but right now i am sending an email to my good friend with a picture of your first 1 peice design and we will see if he gets a good laugh.

If it can't sweep the entire rotor, then why did you say "all" of the rotor is swept? It isn't. Almost ALL oem rotors are NOT 100% swept.
BTW. Make sure to show him the 2 pc version also. You two can sign kumbaya by the campfire and laugh all day. It represents tons more of design then you ever did

Go run to your expert. I've answered all the issues on my own. Apparently you can't even answer questions on the stuff you talk about.

triple ownage. Nismo, make sure to email your buddy this racing brake oem upgrade kit (13"). since it uses the stock caliper, there's no way it can sweep all of it's availabe contact area. Might be why they don't bother with running the contact area as far down as the stock small oem rotor would

Might want to tell him what the oem maxima specs are and that fact that my old car weighs 500lbs+ less than a G37 coupe.

We can sit and calculate and debate all day about what would and would not work. Heavy engineering is involved and some of us on here aren't really in that area of specialty other than the fact we know a few here and there. At the end of the day for us average joe's it's trial and error. So i support the OP for finding a way to work if it doesn't then it is a lesson learned for all enthusiast. Cost to perfromance ratio will hopefully be written down and documented by the OP

Sean,
A perfectly designed 1piece rotor/caliper system would have NO unswept area. The clearances would be super tight between the caliper and the rotor hat. That is not the case with 99.9% of the brake systems out there, including in the akebono setup. There is still space to move the caliper closer to the hat, and have no unused area. Almost no brake systems are like this though, because unswept area doesn't really matter, other than adding additional weight. It is no different than using a caliper that is sized too large for the particular system though. There is no way around this without using a smaller rotor, or a larger caliper, both which have there positives and negatives. There is nothing wrong with Jeff's "BBK" based on unswept area. Not optimal? Maybe. A larger caliper could have probably fit on there, at the cost of additional weight, if the pistons were the same size, but would likely have a higher heat capacity. Is it needed? No. If the system was designed properly with bias kept in mind, then the performance would be fine, albeit with the weight penalty. Using a 1 piece caliper in the first place is already a larger penalty than the unswept area weight penalty.
