What sized brakes on on a s2000 and do they have 2 piston calipers?

Thanks

11.8 inches front and 11.1 inches in the rear. I believe the front is 2 piston (correct me if wrong) and rear is single piston.

sounds right

I was told by Brian at Fastbrakes that the s2000 have 2 piston calipers in the front.

wrong, they are single piston

steven975

yep, both single piston.

one shouldn't get hung up on the number of pistons as it is not a guarantee of quality. The S's brakes are about as good as the brembos on the G35/Z track and they are 4-piston I believe.

it's more of the weight advantage the s2000 has over other cars, and primarily where the weight is...behind the front suspension.

I'm happy with the brakes on my S2000 but I'm converting my 600whp 93 Civic Si back to a total street car with 430whp. I'm changing the suspension back to handle well and need to upgrade from the gsr brakes badly. Do you think the 11" ITR front and 11" Rear upgrade with Hawk or Axis pads would make my Civic outbrake the s2000 or would I need to upgrage to the 4 piston fronts?

Mr. Bagel

I couldn't tell you how to make the Civic outbrake the S. It all depends on the compound and what you are trying to do. Are you trying to go deeper in a corner to cut off the best line for a RWD car on the track in order to gain a position? Or are you just trying to have the best brakes possible?

A lot of this has to do with the pad you are using. Different compounds behave differently. And that said, something that will out perform the other will probably need to be heated up before making such claims, will dust up, and will squeak very loudly, unless you are on it very hard. Not to mention, they wouldn't be that streetable.

Just agressive street driving. Would I see much difference between the ITR calipers and 4 piston wilwoods?

It's not just the caliper that is going to help yield better stopping abilities. The surface area that you are actually using with the brake pads is going to matter more-so.

I don't understand why you are trying to outbrake an S2000 on the street. There is no logical reason for it. Let's assume that you want to out brake and S2000 on a road course. The fact that your civic will have 430whp, and the fact that it is a civic, are probably your biggest drawbacks when it comes to outbraking the S.

Depending on what trim level your civic is, the factory setup, all the way down the the master cylinder might be keeping you from doing so.

At any rate, I'm going to stop babbling here....if you can find out how quickly the S stops from 60 - 0, that will give you an idea of what kind of stopping power you are really up against. There are few cars that can do that feat in under 100 feet. I don't think the S2k is one of them, but I bet it's close.

**EDIT** This just in....found an article on an S2000 modified by Neuspeed. They used cross-drilled Honda Rotors, 17x8.5x48mm Raching Hart CP035's up front, and 17x8.5x48mm CP035's in the rear, with BFGoodrich KD tires. They were able to stop the car from 60-0 in 117 feet. It didn't give a comparison with stock numbers, but, that will give you an idea.

Mr. Bagel

I'm quite sure there will be a great feeling of difference, but there's a bit you can do to the stock setup with just pads & lines. Just by trying out different pads/compounds you can see what suits you best before dropping bucks on a 4 piston conversion. Also, some setups can upset the ABS unit itself. I'm very unfamiliar with ITR setups so I cannot vouch for one way or another.

One other addition: ITR calipers might work, but the pads are expensive since they are the same pads used on the NSX. So, please take that into consideration before taking that plunge. A 4piston wilwood caliper will be cheap for pads and rotor replacements. But if you are on the street, you will not be swapping them out like you would if you went to the track.

I'm not trying to outbrake a s2000. I just have a 04 as my daily driver and it shows me how bad my civic brakes.

Mr. Bagel I need some new pads for my daily driver 04 S. What would you suggest for decent brake dust, better braking, and little noise? What do you think about any stock sized aftermarket rotors? Or a decent bigger brake upgrade?

Mr. Bagel

Just for the street Porterfield R4S's work fine. I dig the initial bite of them. However, if used aggressively, they will dust up quite a bit. Mild use, just typical dusting. Use anti-squeak stuff on the pad backings to help out the noise. EBC's, I don't recommend - not one of their compounds. They never seem to live up to their promises and when they do, they don't stop. Or, give Andie at Cobalt a call, and get some Cobalt (front)/Axxis (rear) pads. They work quite well. Cobalt doesn't have rear pads yet for the S, so the Axxis are needed, IIRC.

1 piston all around calipers and its one of the best braking cars. It's hard to believe but true. My friend's S2000 brakes really good and its totally stock.
Imagine what the car would do with ss brake lines, Motul RBF600, and a good set of pads...

there's a general consensus that SS lines aren't necessary on this car unless the stockers have seen a lot of mileage and harsh conditions. However, I agree with the brake fluid, Motul has worked for me.

I would have to agree. A simple rotor/pad/line swap out is your best bet. I went the entire route and picked up the Endless 6 pot race kit. I can tell you first hand it stops a bit better than the stock S2000 brakes.
Listen to this. My wife and I bought a new 04 civic si and when I first drove it I tried hitting the brakes where I usually do when I am in my S2000 . My god what a difference. I thought the civic was not going to stop. Then I was like there something wrong with these brakes and the dealer was like your not used to stock brake power are you? I guess not. Anyway my point is be prepared to spend about $3500+ for a top notch brake kit. Yeah, it does stop better and my write up just showed you that it did in my case but I could have gotten close to that with a simple rotor/pad/line swap out. Good luck..

I forgot to mention one of the most important parts of a braking system besides the actual brake components...Tires. The stock brake system is more than enough to reach the limits of grip from the front tires, but something not mentioned here about big brake kits is that the main advantage of running a multi-piston setup is for pedal modulation and brake feel at threshold braking. That's what makes the difference when braking from 140+mph. You wont brake in a shorter distance with a BBK on the s2k, you'll improve brake pedal feel and will feel a lot more confident when braking from high speeds.
