Simple 6 pot brake setup
Please help me understand your math. When comparing piston volume, shouldn't all of the pistons you are replacing be considered?
pi*r^2 *2 is for 2 pistons, not 4 as stated
So the evo caliper pistons are 46mm and 40mm. Using the equation above the evo calipers have
46mm piston diameter = 1.81102 radius of which is .90551
40mm piston diameter = 1.5748 radius of which is .7874
since we are only accounting for the number of these pistons on the car totally one can say that the evo has
(46mm piston) + (40mm piston)
1660+1254.8=2914.8mm/sq piston area for the evo caliper by calculation
for 1 caliper, you would want to multiply by 2 to make it 5837 mm^2 for one caliper and 11674 mm^2 to include both calipers you are replacing
This would end up being 12240mm^2 for a difference of about 565 mm^2
Seems like a significant difference
34mm piston diameter = 1.33858 radius of which is .66929
36mm piston diameter = 1.41732 radius of which is .70866
38mm piston diameter = 1.49606 radius of which is .74803
pi=3.1417 x (.669x.669) x 2 = 2.81220478 or just 2.812 sq/in of piston area if there were 4 34mm pistons
doing some math...

I really want to know how the rears will go on, so I am bumping this thread.
Also, with just the fronts, while tracking, I would like to know how this offsets the brake balance without upgraded rears.
Thank you for the write up!!
Update please!!!!

Really impresive Swap.
Im going for it.
2 questions.
Can i fit the 18Z MODEL, what is needed, 18 " wheels only ?
I want to install with metalic brake lines, do i have to made customs ones ?
Regards.

If someone knows any shops or vendor that'll willing to build adapters like the ones they have s14's that'll be perfect. Similar to these

the only way to build a bracket for this would be to use a larger rotor because the bolt holes just about line up. It would easier to buy an aftermarket radial mount caliper from Wilwood and build a radial mount bracket to bolt to the spindle.
