I found it interesting that in the (road and track) SPEED mag artical "Tuner S2000 Battle Royale (nov/dec 2005) -- only the comptech car had any braking improvement over the stock s2000.
the 80 - 0 braking results:
Comtech ------- 205ft --brembro kit 13"frnt/12.7"rear
05 OEM --------- 207ft
Mackin -----------216ft --project mu 355mm frnt
AEM --------------240ft -- hawk padsfrnt / axxis pads rear
David Karner -- 260ft -- Performance Friction padsfrnt/rear
Greg Park -------279ft -- project Mu 345mm frnt / mu pads rear
seems like the comtech kit kept things balenced front and rear --
really interesting artical for those who missed it...
Keep in mind that tires have a LOT to do with stopping distance too. So these results are not conclusive.
I have destroyed a set of brake rotors in one track session with my greater than 300hp
S2000. I was running R4 pads that do creat a considerable amount of heat. Cool down proceedures didn't prevent the rotors from totally cracking. That was with brake air ducting too.
I am currently running early ('00-'03) factory pads on the street to avoid the dust.
I've been running Motul 600 for 5-1/2 years with annual changes and don't think about the fluid at all.
The addition of stainless steel brake hoses made zero decernable difference in pedal feel.
Good basic summary Drew.
I am planning to change rotors to decrease weight in the future. There are several pounds of unsprung weight to be removed from each corner.

The biggest factor in braking distances between similar cars is wheel and tire sizes. The S2000 comes with capable brakes, needs only a pad and fluid change to manage the heat for a very track capable setup, but a set of fat race tires will make all the difference in distances.
Your absoluetly correct. Tires are the key with braking distances IMO.
Bottom line is a 4-12 piston BBK is overkill for any S2000 on the street. I agree with the others that the OEM kit and maybe a simple pad change and fluid change would do wonders.
I had a few BBK applications and the biggest problem with these is finding wheels that will clear and still utilizing OEM (at the minimum) size tires. It got tough with the larger BBKs. Overall I was happy with them even though they were overkill for the car. Half price always helps.
[QUOTE=slipstream444,Jun 17 2006, 04:13 AM] You're missing the point - a car with 300hp has the ability to accelerate much faster than a stock car - this performance increase puts you in high brake energy situations much faster, and more often than stock.

They cracked because they are cheep oem rotors that are drilled. It depends on the material of the rotor as well.
OK... I should probably amend the article to add that slotted rotors are an advantage if you've got Roger Penske's parts budget.
For those of us restricted to buying rotors that cost less than our monthly mortgage payment... solid rotors are probably the best choice for performance applications.
(btw... the above poster who commented about OEMs rusting is right! My one complaint about them. A good alternative is the Cobalt rotor available through Go Fast Lab. It's a bit costlier than OEM and offers no performance advantage, but the centers are nicely painted... they don't rust.)

can anyone else confirm that there is no differance in pedal feel when changing to SS brake line. when i installed SS line in my integra it made a HUGE difference in the pedal feel.
I will definetly second that. When I put SS lines on my GS-R it was night and day difference. My brakes seemed more on/off
