That's what they look like to me too. It's friggin math!

Here goes:
Z32 rotor is 280mm, pad is 50mm (from FSM). So, R1=140mm, R2=90mm.
Total swept area is 36128 sq mm.

350Z Brembo rotor is 324mm with 3mm of pad overhang (47mm pad). So, R1=162, R2=115.
Total swept area is 40900 sq mm. That is a 13% increase in swept area.
If the bracket put the caliper in the right spot and gained the 3mm of pad back, this number goes up to 43039 sq mm, and 19%

Just a little fun...
The real deal 350Z brembo setup is 324mm rotor with 53.3mm pad. R1=162, R2=108.7.
Total swept area is 45328 sq mm. That is a 25% increase over stock Z32.

And just to rub it in... Look what happens when we calculate % increase by just using the rotor diameters... (324-280)/280 = 15.7% increase. Pretty friggin close to doing it the long way, eh?

So Cliffs notes.
1. This "hack" setup increases swept area by 13% over the Z32 rotor. Yes, it'll be more effective in braking.
2. You're only getting about half the benefit versus running actual 350Z brembo calipers (regarding swept area).
3. Compare my corrected bracket number and the 350Z number. This is the difference that the extra 3.3mm of 350Z pad adds. 5%. It does make a difference, but not by a whole lot.


Hey Burgy, is batting average hits / at-bats, or do you take out the walks. What the hell is slugging %? Honest questions.
