Anyone know who makes cross drilled slotted rotors that are OE size for the R?

 

Look on Ebay I have seen several But EBC makes some

Cause I want them.

What kind of improvements do cross drilled slotted rotors provide over stock rotors?

Simple Less brake fade better Heat Disapation


EBC GD & TGD Series (Track & Street)

EBC�fs latest addition to the family, the new TGD discs, are British cast and machined using a high quality alloy designed to run up to 800/900 degrees centigrade (glowing red hot) and still run true and stay straight. For light race, rally and trackday use. New 4-spot drill pattern shows difference with standard 3-spot GD series. Together with V4 Greenstuff which help to reduce rotor temperatures, you will be hard pressed to find a better standard size disc/pad combo for your car.

 

What does it matter? Why do so many of you answer my question with another one? I think only one person gave me a straight answer.

 

Thank U for a staight answer. I'm just researching my options. Thanks again.

 

No problem. I have used the Brake pads and they are worth every penny IMO.

I think The Question about what improvement over stock was just a Legitimate question.
Some think every purchase for your car has to be justified by some performance usefulness
I have not used the Rotors but in reading the writeup on them I can see a few things I do like about them. The Dimples instead of being cross drilled is IMO a pretty good idea so as not to weaken the structure of the rotor. The manner inwhich the rotors are also vented near the hub is very nice as this will allow the rotor to cool faster.
I can tell you that the EBC pads get really HOT and you need a good rotor to handel heat without warpage.
EBC claims that their rotors will not warp under hard braking conditions. Well anyone ever use them? Word to the wise DON'T use EBC's with AEM Big brakes. THEY WILL WARP!!!
http://cgi.ebay.com/ebaymotors...33564 Ractive makes these. I think if you want them for performance then go with a Brand Like Brembo or the EBC if you are going to use them for normal braking duties and Show then you can go with the Ractive or APC

i think the cross drilled rotors will help cooling the rotors.. but i also heard it will cracked.. haven't try those myself.. as i remember Brembo makes some for ITR OE's size..

 

A friend of mine has got 2-piece Alcon rotors cross-drilled on his EF9 (EDM EE9) with NSX brake-calipers.
On track days they keep there excellent "bite" and here in Holland are not that expensive.

 

Heres a good list of ones for the ITR:

For the ones that are goldish colored. Do they change color after use, or do they stay that color?

[\QUOTE]

Cross Drilled rotors do not help with heat disapation, in fact they make it worse because you have removed material from the rotor. Crossdrilling used to be used when pads outgassed, modern pads do not outgass.
Read this http://www.teamscr.com/rotors.htm

Crossdrilled and slotted rotorsgive a differnt brake peadal feel but in almost all testing I have seen they do not improve stopping distance, if you want them for looks that fine they will be fine for street use, however they are more prone to cracking than non crossdrilled and/or slotted rotors.

For the driving level of 98% of the people on this board... solid rotors will provide all the braking you will ever need.

If you are worred about gas build up under your pad material then you could look into slotted rotors.

 

Thanks for the straight answer George

The reason most of the users will dance around the issue is because most of us know that even in racing applications, drilled and/or slotted rotors do nothing other than reducing the effective braking area.

•They do not help you stop faster in virtually all situations.

•Rotors are an entirely expendable item, and you're making them more expensive than they have to be. If you use your brakes so much that you need to think about better brakes, this is probably not the right step to be taking.

•Modern brake pads no longer gas the way that performance brake pads did in the old days...so one of the big reasons for slotted/drilled rotors no longer exists.

Just so you know, I'm not aware of a single Honda Challenge car that uses slotted or drilled rotors.</TD></TR></TABLE>

This topic keeps coming up and the usual responses are exactly what George said, that slotted/drilled rotors do nothing for braking.

I don't think I agree and (no offense intended) I don't think that the ECHC is the best place to look for answers. If this is true then tell me why cars in the WRC, Speed Challenge, JGTC, BTCC, and other professional series are using slotted rotors and sometimes drilled rotors?

The cross drilling helps with water and mud removal (WRC style).

I suspect that the brake systems on the race cars mentioned above are tossed after each weekend and the calipers are rebuilt.

Does anyone here toss their pads and rotors after a weekend event?

 

I'm not saying that people like us would ever need them - I was simply pointing out that the canned answer "in racing applications, drilled and/or slotted rotors do nothing other than reducing the effective braking area" is simply not true.

But I do agree with your points that for weekend racers they are probably not needed.

 

I installed a pair of the above EBC 'sport' rotors/discs early this year..... I've have been very pleased with their performance, on both the road and track!!

Plus they were cheaper than the OEM Honda ones (well at least in Australia).

 

I agree George. I guess I just don't like blanket statements that lead people to believe somthing is true in all situations.

I love the ECHC btw...

 

I am sure most of them change thoer Rotors out before every race, plus a lot of them get deal through differnt sponsers on slotted and cross drilled, having talked with Matt Nicholson of carbotech, he says even in extreme conditions that brake pads do not outgass any more, ususally they do it once during brake in, but after that then never do it again, with higer speeds slotting may help as pads under heavy use are more prone to glazing. Also I belive that the rotors tehy are using in most high profile racing class are cast with the holes in them where options like powerslot and others are drilled after they are cast, which to me is not something i would want on my car period.

 

on my R i use brembro cross drilled and sloted. i bought them at jdmhondaparts.com

 

and let us not forget, the 'cross drilled' rotors used by the pros are rarely actually cross drilled, more likely the rotors are cast with the holes in them to retain the strength that would be lost when drilling a rotor

 

The Answer to your question..way up there at the top is NEUSPEED.. they make them.
