Big Brake Kit Picture Thread!!!
considering they are engineered to have the same piston volume, ie more pistons but much smaller so the end volume is identical to stock. then they have the exact same clamping force as stock so no real "extent" its simply how it is.
if you want more braking power you have to retrofit calipers from another vehicle on the car that has increased piston volume.
for instance i guarantee the veyron has more piston volume so they will stop the car sooner, however im willing to bet money calipers for say a miata have a smaller volume so even a 10 pot kit for a miata(if it even exists) would give poorer performance then stock. everything for the z is engineered(or everything i have seen) to have identical piston volumes to stock.
if you really need increased clamping force though which i highly doubt thats a single car on this forum. abs causes your car to have about 30% less clamping force but again i doubt any car here has reached the limit of pads, instead they are seeing the limit of tires.

Robert - lets take a ride, you cane drive if you want.
I have both quantitative and qualitative evidence my
Car stops fast as fffffffffuk. I can only imagine what it'd
Be like w a proper set of race slicks.

You're using a brake kit designed for a much bigger, heavier and more powerful car. Robert K's statement is right when talking about kits that are designed for a specific car. You're application doesn't apply to this.
if your abs is not activating when you have a bbk then you either ****ed it up or your have reduced your braking power. the computer has absolutly no way to tell you put a bbk on the car it monitors wheel speeds to activate the abs. if it actually increased your braking power then it would be activating MORE. learn how brakes actually work, they ARE engineering with the same piston volume so that you can swap in just a front kit without the rear next time you wanna try claiming they arnt call the manufacturers tech department. go ahead and take your car to a place who has the actual tooling to measure the performance of your brakes(i know ssbc will do it for a price.) your expensive *** bbk isnt going to produce any more clamping force then stock without a kit for a different vehicle.
now you would think that more area on the brake pad would result in more clamping force but that follows the same failed logic as a bbk increases your braking power. sure the pads are longer so you would think there is more area, BUT the force applied to the pad itself is the same as stock, you dont have a smaller master cylinder to increase pressure, and unless you upgraded to a different booster or longer pedal your not getting anymore pressure there either. so you have stock pressure at the pad again call the manufacturer since obviously you have no idea what your talking about and dont believe me. so what happens when you take the same pressure and apply it to a larger surface area.................... oh **** less clamping force. so any benefit you gain from increased pad area is negated by itself from the loss of clamping force, resulting in a stock performing kit.
the oem pistons might be a single piston but they are much much much bigger then stock(and actually 06-08 are dual piston front)
sorry i know you agree they dont help you stop sooner but your post is just flat out wrong.
also that link your talking about is repeatedly talking about front and rear changes as well as swapping calipers made for different vehicles. the 350z kit is made so you can place it on the front of a car without the rear because the piston volumes are the same.

Big Brake Kit do not have the same volume when comparing to OEM 350Z, especially non-Brembo, calipers. The OEM calipers are a single piston pull type brake caliper. And the pad surface area is considerably smaller. Therefore more braking force is applied over more of the rotor. Also ABS does not activate with a after market big brake kit.

I've had my StopTechs engage my ABS. LOL I was just stating adding a BBK should not effect your ABS. ABS is activated via the wheel speed sensor, not by brake pressure. When the speed sensor (position sensor) sends a reading of a wheel locked up it activates the ABS. Therefore a BBK should not effect your ABS system.

I plane on getting a BBK sometime or another. But im not sure what color calipers to get that will match the Solar Orange 
Maybe just black. I love red but that is a no go with orange. Any ideas?
Maybe the bronze wouldn't look to bad?

The clamping force and brake pad surface area is not the entire equation. BBKs normally have a larger diameter rotor allowing for the caliper to act further away from the center. By doing this, it has more leverage, thereforce less force is needed and less heat produced.
As an example, spin a bike tire and try to stop it by grabbing the spokes with your hand, first near the center, then near the outer. You will notice that it is easier to stop it by grabbing the spokes further away from the center (outer). The BBKs work with the same principal.
