I am running Orange on my 996tt at track events but I think I am still overheating them since I end up with brake shudder in later run groups and/or when temp is very warm. Have ordered but haven't received Cup ducts and yes I have bedded them in properly at least according to my mechanic and the stoptech articles.

Should I try the yellows or another brand of track pads with higher temp threshold? Have sorted out the engine (stage II setup) and suspension mods (Cross, GT3 bars) but the brakes are still not inspiring 100% confidence.

Any educated opinions welcome...let er rip...

 

I am no expert but I asked several experienced drivers before choosing track pads. I went with the Pagid Yellow and they are great. At the track they stopped great and I experienced no fading. And despite what I expected, they worked fine on the street. Not only did I use them to get to the track and back but left them on for a week after the DE with no issues except glaring looks from other drivers as I squealed to every stop on the way to work.

 

Thanks for the feedback - my problem is overheating the Oranges, especially on shorter tracks, and then I get pad transfer and shimmy on braking. The yellows may be better compound and has higher temp threshold so maybe I'll try them next. I have gotten used to the wierd looks when I roll to a stop

 

Pagid Yellows get my vote. I have no other street pads, they might squeel a bit, so what

Of course the brake disks don't like that kind of pads but it's not a bad price for having great stopping power...

Performance Friction has also a good racing pad but haven't tested it myself.

 

I suggest performance friction 97 compound. You won’t be disappointed. I use them on my car with no issues. They also make replacement two piece floating rotors for the turbo.

 

I went to the Performance Friction site and they say they don't have any parts for Turbos. Where did you see rotors for the turbo?

 

Front pads:
7818.97.17.44
Rear pads:
0776.97.17.44

I have to double check the rotor part numbers but they should be:
350.068.87 (L)
350.068.88 (R)

 

+1 for yellows. Blacks if you really want to stop hard.

 

Get the Yellow RS29's. They are better then the orange pads I used to use and I get at least 2X as much track time out of them...

 

I dont think changing your pads from orange to yellow is going to stop them from overheating.
that is a function of cooling and boiling temp of the brake fluid.
I recommend upgrading brake fluid to Castrol SRF, adding the GT3 front cup ducts while also concentrating on your driving and braking technique and I think you will be happy with your current set up.
It is what I have I and rarely have fade.
good luck

 

It depends on your goal...if you want to put down a hot lap, then stick the yellows in there and go for it...if you want endurace, you should do as Tom said and put some SRF, stainless lines, ducts AND change your braking style. At my recent clubrace, I went through a set of yellows in 1.5 days (they were NEW and I did that). That was for the practice and sprint races. The next day, I changed to Pagid Orange for teh Enduro and modded my braking around certain corners that werent necessary to bomb in and added atleast a day or so of use to the pads. That said, the turbo, no matter HOW you take it, will always have its brakes as the weak point of the car. The thing is heavy and unless you are running a 3k lb turbo or lighter, your gonna cook the brakes one way or another if you want that fast lap every time.

 

first, use yellows, rs19 or 29.
2nd, it's highly unlike you overheated the pads. you probably didn't bed them in right and caused some weird pad mat transfer which induces judder. but the judder DOES NOT reduce braking power. it feels funny, but you still have all your braking power, just igore the judder, the material will burnish away and it will feel normal again.
3rd, use SRF or motul 600 fluid just for peace of mind.

 

Thanks for the feedback, guys...I do have the cup ducts on order but will have to wait till next season to try them out. (already have SS lines, and the race fluid) I found that I usually do not have as much problems if I am running a relatively open track with no one holding me back, that way I am on the brakes hard but quick so they have time to cool a bit on the straights. I find that when I am in a train, the braking is less efficient and I am on them a bit more so it isn't colling off enough. Don't think I am really gunning it...I was turning 2:15 to 2:20 at the Glen. I am not experiencing fade at all and the braking power is still all there - just kind of annoying to get the shudder towards the end of the track sessions.

I have driven it a bit in local traffic and have abraded down the transfer (lots of cold braking) so the vibration has gone away for the most part. I probably will try to yellows when these oranges are worn down.

 

I have the same problem.

I am running Brembo 350mm floating disks on my 996tt with the gt3 6 pot callipers.

I have used the Pagid Oranges all round and have braided hoses and Castrol SRF.

I get the same juddering after a few laps, but i do not get any brake fade, so I presumed the disks were getting too hot and ordered some Cup ducts from Carnewal.

Once fitted (real easy to fit) I went off to the Nurburgring and aaaargh, the brakes didn't warm up as quick as before (took half a lap before they worked fully) but the juddering was still there.

 

I hate shuddering and juddering!!!
