which part is lighter rotor or caliper

 

Caliper definitely, not sure about the rotor.

 

K sports has rear for us. 6 piston front, 4 piston rear.

i think..

i'm sure endless has one for s2k too. 12 piston up front, 6 piston on the back.

you could take g35, STI or Evo brembo and put it in s2k... supposely.

 

Isn't it proven that big brake kits are that much better than the regular brake kits, they only stop better by like a few feet?

 

BBKs arent really meant to increase stopping distances by much, the point of the larger rotor and caliper is to be able to absorb/diffuse more heat, reducing brake fade after multiple hard laps.

 

the ap is one forged monoblock though right? i wouldn't trade that kinda strength for anything

 

where did you hear this? there's no lack of bbks for s2ks but there is a lack of ventilated rotors and ebrakes in the rear coming with kits

if you know about evo brakes going onto s2ks do they retain the evo ebrake assy? because that would be phenom

 

not to get too off topic here, but...will an upgrade to cross-grilled rotors improve performance over the stock rotors? how much do aftermarket rotors go for? honestly, I'm vaguely interested in doing this soley for the bling factor. am I wasting my time and money?

 

cross drilled rotors don't offer any benefits really. especially in light of current pad technologies.

classically cross drilled rotors were used for increased ventilation and increased pad scrubbing, sometimes for race applications where the longevity may not matter.

check this out for reasons why you might not want cross drilled.

 

you have to retro fit the caliper into a rotor from brembo for the rear. there was a guy who I talked to briefly that had one, but he bought this rotor kit from some company, it's basically the same layout as the s2k rear, but rotor surface was different. blank.

just remember, cross drilled rotors mean, less surface for brake pads.
