Just wondering if it's worth to upgrade from my ITR brakes to a S2K setup. I know that I will obviously be getting a larger diameter rotor but I have read that the ITR pads are actually bigger than the S2K ones. So what good would the bigger rotors do me with a smaller pad? The only positive that I can see would be better heat dissapation. Anyone care to comment? Pros, cons, or whatever.
Thanks.

 

S2K rotors (at least on the AP1) are the same diameter as ITR rotors, just 2mm thicker due to larger vents between the sides. 1st Gen NSX rotors and some Legend GS rotors are also 11", but are 28mm thick, vs. ITR's @ 23mm and S2K's/Prelude VTEC's @ 25mm.

S2K brakes are those used in the Mugen Active Gate setup.

I rock the Legend GS brakes. The additional mass and venting handles a bit more heat. They use the same pads as the S2K and ITR brakes, but the rotors are markedly pricier.

 

Simple Questions:
Why do you have to change the current stock brake setup?

What problems are you facing now?

What are you trying to accomplish that the current setup fails to do for you now?

I am not saying to not try a different setup, just trying to figure out why you want to change and what data have you acquired to prove that you need a change in your setup.

 

^ yeah what he said.

i'd just keep the stock itr brakes and get a good set of pads and a nice set of tires to maximize the brake force and give good coefficient of friction to the road. That would give you better of a performance gain over just getting s2000 brakes and use whatever tires and normal pads

 

the stock itr brakes are amazing in my opinion. but being im a mugen ***** id love some mugen active gate brakes

 

keep the itr brakes. i had an s2k and i think the stock brakes on an s are by far not as good as the itr ones!

A good number of people will argue with you on that one, myself included. You're entitled to your opinion though

 

let's let Dave sort this out.

He has less posts than you and me. And I like it when he's active in here

Simple Answers:
I don't have to.

No problems.

Stop faster.

The main reason I'm considering it is because I have a set of S2K calipers just sitting here and thought I might put them to use.

And I don't think there is any conclusive data that can prove or disprove that I need to change my current setup. I was just trying to get other people's opinions who have tried or experienced both setups and would base my decision on their input.

Thanks for all the comments.

I already have a decent set of tires. I need to replace my pads whether I use the S2K or ITR. What if I used the S2K with my decent tires and better pads?

 

Dunlop Direzzas + Carbotech AX6 = &lt;3

save the money and get BETTER set of tire, and GOOD pads. spend the rest of the money on dope

Good luck. Honestly you are wasting your time for what you need. Sell those S2000 calipers on S2KI, HT, etc and use the money for better tires and/or pads, both of which will make a far larger difference, although I wouldn't suggest too much pad since it seems you are just driving the car on the street.

As for S2K brakes being better or worse than ITR brakes, ITRs out brake me with equal pads, while the ITR brakes may not be technically better, they are better suited to the application, S2000's are underbraked IMO.

I'm not sure how they bolt up on an S2K but when you bolt the S2K calipers onto the ITR spindle you have to use an 11.8" rotor instead of the standard 11.1" ITR rotor.

Also everyone who keeps saying get better tires and pads, again I already have a good set of tires (g-force T/A KDW) that are practically brand new, so no I'm not gonna go and buy others just because, and I need to replace my pads whether I keep the ITR or use the S2K brakes so why not just get better pads for the S2K and utilize those brakes. And what money would I be saving? I already have the calipers that didn't cost me anything and last time I checked tires cost more than pads and rotors.

And out of everybody that has commented, have any of you actually had or experienced S2K brakes on an ITR? It's people who have actually felt the effects of the two that I'd really like to get opinions from. I appreciate everyone's opinions but so far no one has said "I've used the S2K setup on my ITR, and they are better/worse IMO". Not necessaraly those exact words but you get the idea.

Thanks again everyone.

I don't think you'll have a great deal of success with this. The problem is that the guys who know what they're doing tend to not make this modification, and the guys who DO make it tend to not know wtf they're doing when it comes to turning a wheel.

Your tires aren't bad, what brake pads are you using? That might be a simple enough upgrade that'll make you happy.

The AP1 S2K uses 11.1" X 25mm front rotors. The AP2 S2K uses 11.8" front rotors.

I don't exactly know what you mean by this. The main thing I'm trying to do is lower my 60-0 distance. So what does turning a wheel have to do with it? To answer your other question I'm running OEM pads. I was probably gonna get the Carbotech pads as suggested by Slofu earlier.

Perhaps theres a reason for that. Its not necessary. Are you tracking your ITR? The stock ITR calipers and rotors with a good pad and fluid is more than enough, all the way up to the Honda Challenge.</TD></TR></TABLE>

It's not necessary to do a header or exhaust either but people do it as an upgrade. That's all I'm trying to do is upgrade. And no I'm not tracking my car. It's my daily.

Maybe the calipers I have then are an AP2 set but I could have sworn they were from an AP1. When I put them on using the ITR 11.1" rotor the pad was only half way touching the rotor. Then I got an 11.8" rotor and the pads made full contact. I got the calipers from an 02 s2000. So like I said before maybe they bolt differently from the s2k to the itr.

 

Braking is a part of driving. People who know how to drive well will also know how to brake well. Conversely, people who DON'T know how to drive well will also not know how to brake well. As such, people who don't know how to do something well will have somewhat worthless opinions on the subject they fail at. To simplify that, don't ask a third grader to explain quantum mechanics.

Since both calipers use the same pads, why not try out some better pads and see how it goes? For that matter, you could just try the new calipers and see, since you already have them. Worst case scenario, you're out a few bucks for the rotors if you don't like it.

Nice analogy . In regards to your comment though, I think you are trying to simply categorize drivers into two different groups, skilled drivers and unskilled drivers, and there are too vast of amounts of variables to consider when classifying a driver's skill. With that being said I'm quite adequate in my driving abilities but still like to experiment with other options to better improve my driving abilities and if this is a possible way to do that, then I think it is worth researching and trying.

Also I don't think they use the same pad because they all have different part #'s.

AP1 S2000 - 45022-S2A-000
AP2 S2000 - 45022-S2A-E50
DC2 ITR - 45022-ST7-R02

Oh yeah and before when I said I didn't know what you meant by "turning a wheel" I interpreted that as braking while cornering. Sorry about that, makes sense now though.
