want to upgrade my brakes for my si but dont know which components to get, i want to keep the stock si rims on the car, i want to enlarge the back brakes to be the same size as the front brakes, i was looking for maybe a good slotted an drilled rotor with a better brake caliper, pads and some stainless steel lines, just want to improve breaking capability will keeping the si stock rims, just hadbrand new tires put on also. also was wondering is a master cylinder off a gsr bigger than an si master cylinder or would i have to go with a type r master cylinder or is the si master cylinder big enough for what i want.
the best and only real way to reduce braking distance and braking capability is to increase the actual size of your rotors, which obviously isn't possible keeping the stock wheels :-\
cross drilled/cross slotted brake discs merely help make your brake discs LAST LONGER. reduced amount of heat = less wear = longer lasting discs. one good thing is that u got new (hopefully better) tires, what kind did u get? you'll notice better "braking" in a sense... just from the new tires, even though u didn't change your braking system.
but wouldnt the bigger brakes in the back and calipers with more pistons help reduce stopping distance, i dont want massive braking capabilities i just want something for the road course and improve better breaking overall while keeping my stock rim and reduce stopping distance a lil bit.

yea, thats what i said

really good tires are your best bet if u want to keep stock wheels.
I thought I Would chime in here. The best way to get better stopping power is one of a few things:
tires - remember these are the only things touching the ground which is helping you to stop. I know so many people who ask why their car cannot stop and I ask what tires then have and they tell me Pep Boy specials.
larger rotors - more surface area for the brakes to clamp onto and also dissapaiting heat better
grippier brake pads - same as above
replace the stock brake fluid - old fluid will get air bubbles and water in the lines
stainless steel brake lines - rubber lines will expand like a balloon under hard braking which decreases the effectiveness of your brakes
lighter car
lighter wheels - less rotational mass means your brakes don't have to work as hard
That's about all I can think of. I know my brakes are working fine cause even with DOT racing tires I can lock up my brakes which means my tires need mroe grip

Be careful with this one. Often times cross drilled rotors can warp and crack sooner than solid discs. The drilled holes are great places for stress cracks to form, and with less iron to absorb heat, they can actually warp sooner. I bought some slotted and "dimpled" rotors from the Tirerack.com. Within 2 months they were badly warped and I had to mail them back. I didn't race my car or abuse it anyway. Just my experiences...
