Just wondering - if I wanted to lighten rotational mass on a stock 2000 ITR, could I not install lighter rotors all the way around, instead of buying more expensive light rims?

If so what rotors do you recommend for street use applications that are lighter then stock and fit properly.

Thanks in advance.

 

ATS c/f brakes..but they literally cost an arm and a leg.

 

For less than the cost of either you can do driving schools which will make you faster than either part. Learn to drive before wasting money on chit like this.

 

And what makes you think I cant drive??? Is it because I asked a question??

 

Nope. It's because 99.99999999999999999999999999999% of the worlds population can't drive. Trust me, you can not outdrive the car at this time unless you are a very experienced race car driver, which judging by the fact that I never recall you talking about road racing your car, I'm assuming you are not. Mods will make you faster, but learning how to drive the car will make you even faster than those mods made you. If you want to waste some money, at least waste it in a good way and install a new flywheel and ats final drive.

 

 

Thanks Dave-ROR, I didnt know that....

I do, however, want to upgrade the braking system on the car, I thought, if I can do this as well as reduce rotational mass, then I would be happy.

It's funny how you just assume that, because I do not mention track racing, I must not be experienced....

Thanks for all your wonderful help....

 

I'm not sure you want to lighten your rotors. You want rotors that work well w/the metallic-makeup of a brake pad. If you get some funky ceramics or carbon, you'll drop big big money and probably require specialty pads as well. If you think you don't want to spend money on lighter wheels, then forget lighter rotors. Dollar per pound, you'll get batter value w/the wheels easily. The cheap option of thinner, smaller rotors will just overheat and not brake as well - a poor compromise.

SSR Comps or Kosei K-1's if you need it on the cheap.

 

I was wondering if someone makes a rotor with the same overall dimensions, however, are lighter then stock rotors...

Of course I do not want a rotor that is smaller... as well I am not going to spend a couple thousand dollars a wheel for a carbon fiber setup....

Just thought maybe, some manufacturer like Spoon, Comptech, Mugen has produced a swapout rotor kit that is a little lighter then stock... guess not...

 

Do you track your car? Why do you need to upgrade the brakes? For what purpose do you need better braking? If we know what's the problem with the stock brakes, we can provide better solutions to help you.

 

spoons are nothing but moded stock rotors. i picked up a set of stoptech (sp??) this weekend and they are ALOT lighter then than the spoons. they were very nice looking and had some nice cooling stuff too. hit the link in my sig and give dave a call, he had a set but i think they were already sold.

 

Then don't remove metal mass from the rotors or keep the stock calipers. Get spoon calipers. Removing weight from the hub area is a lot less effective then at the outer wheel circ. Either way, that'll help during launch with very minor improvements elsewhere. The ATS FD is a much better item.

I bet I'm right too. No offense is intended, but I bet you every single person who tracks and/or participates in sanctioned road racing events agrees with me. I love people who think they are the **** cause they can drive fast on the street.. lol

Maybe one day you will see that I *WAS* trying to help you out, once you get over taking offense to my "attack" on your driving skills. It amazes me that people defend their driving skills as much as their **** size.

BTW, I am ***FAR*** from the best driver on this board, and I FREELY admit it.

 

dave-ror is an azzhole most of the time, but he means well.

To reduce mass, I'd say you're better off going the lighter wheel route, brakes are a pretty direct wear item, spending lots of extra $ on something that's designed to wear away is about as smart as smoking, or just burning money outright

If the money is burning a hole in your pocket, seriously consider a driver's school or High Performance Driving Event like a funday or something...you will learn alot more at the track in one day than you can ever learn on the street. There's a reason we're all so keen on it....it's true. The Stock type R has a great deal more potential than people realize, they jump into mods to make their car "faster" whithout actually learning how to drive faster. This sums it up pretty amusingly: https://honda-tech.com/zerothread?id=123334

 

check out fastbrakes.com because he has a 2 piece ITR rotor.
--->aluminum hat bolted to a 1 inch thick, 11" o.d. rotor... lighter than stock.
I have these on my Integra GSR, and believe he does have them for ITR's.
I imagine Wilwwod can also come up with a lighter 2 piece setup for you.
Also you might want to look into Wilwood caliper to lighten the calipers... unsprung weight is a nice thing to minimize.... better handling.
HTH.

 

One more consideration:
By using lighter rotors you decreasing thermal mass. In other words, lighter rotors cannot absorb as much heat as hevier ones, resulting overheting of brake system.
Why is it importaint for the street use? If you try an emergency stop from highway speeds (~100+MPH) with light rotors, you will experience brake fade.

IMHO upbgrading rims is better.

 

well a reduction in thermal mass would effect repeated braking.....
--- not a one stop stomp---
I noticed a huge improvement in brake feel and brakepower and havent experienced brake fade... on the street (so far)... but I try to run fresh fluid and pads. Also I had a GSR to start with.
Because Aluminum is lighter does it necessarily effect thermal mass?
Or is lighter Mass different from less Thermal Mass.....?
In fact I have more metal between the pads.... with my 1 inch thick rotor.

Note, I am pretty sure on the track my setup would NOT be superior to oem ITR rotors and Wilwood/Spoon calipers.

 

I am an *******, never claims I wasn't.

Virtos:

 

owen: you are using a thinker than stock steel rotor still, I don't think the decrease in thermal mass will be as noticable with your setup as with some others.

 

what? thinker? is that thicker or thinner.... you stumped me with that tricky typo.
1" is thiCKer than oem itr front rotors...... it barely fits with new pads too...
Okay, I gotcha, my setup may have less of a decrease in thermal mass per actual mass.
so, uh, yup. All I gotta say is fastbrakes is good stuff.

 

Thicker of course

 

We have a winner. Stop Tech 2 piece floating rotors. These fit stock ITR calipers and are at least 2 lbs less than the Spoon shown in the pic. Price is $425 per set. Available now. Also, these can be done in a 4-100 hat provided an ITR caliper is used.
Stop Tech vs Spoon Vanes

Thanks!

 

You just need to learn the rules around here, that's all.

1. If you want to make your car faster, you automatically don't know how to drive.

2. If you want more power from the engine you must be one of those people who street races in school zones.

3. If you think a Friday night of bracket racing is fun you maust never have ran an autox or lap day (even if the first time you drag raced was over three years after you started autoxing).

Nomex suit on.

 

When you do a series of repeated brakingyou will overhet them if they will not cool fast enough. On the other hand, when you braking from the gigh speed, cooling is minimal (not enought time to really cool), so almost all of your car energy has to be absorbed by rotors and pads. Then you want more thermal mass.
Thermal mass depends on two things: actuall mass an the material of rotors/pads. Size and shape affect only cooling.

Hope it makes sense.
