Track Pads Questions

[Racer Boy]

I've been researching pads for my '02 base Boxster, and have some questions for those of you who track your cars. I do three or four track days per year, usually at SCCA Track Night in America events, because they are cheap (but you never know what the other drivers will be like; it's the wild, wild west at those events). That means 60 minutes of track time per event.

I currently run EBC Yellows, which I've come to find are unsuitable pads, as once they get hot, you get a terrible shuddering at all the wheels. It's my experience that they don't fade, because you can't brake hard enough to really test them without the car shaking so badly that it's very worrisome.

I would consider myself an advanced driver, since I have lots of years of racing experience. In a normal track day, the only cars that pass me in the advanced group are much faster cars (Mustang Cobra GT350s, turbo'ed Miata's, later model 911s, those damned WRX's) that usually are using R-compound tires. For the upcoming year I've acquired another set of wheels that I'll be running Hankook RS4's on. My aim is to just have a good time and be able to give myself and the car a decent workout.

My car has a ROW M030 springs and shocks, with as aggressive an alignment as you can get with stock suspension components. I want the car to remain a pleasant street driver, with track duty not being it's primary mission.

From my research, I've narrowed my choices down to Pagid (Orange, Yellow, or Blacks), or Raybestos ST 43 or 41s. I'd like to use the PFC 08 pads, but they aren't available for base Boxster brakes. Since I'll probably also run the pads for street use, I want something that works okay at regular temps and isn't terribly noisy or dusty, but I know that with track pads, it's a real compromise.

From what I've read, the Hawk track compounds are very hard on rotors for street use, so that is why I'm not looking at those.

What say the 986Forum mind-hive? Which color Pagids do you find the best? Which Raybestos compound is favored? The Raybestos are less expensive, but there isn't a huge difference in price. If you have any other reasonable suggestions, I'd like to hear them!

I have used Pagid Orange. Never have had a problem at the track. A litte noisy sometimes, not too bad.

[trygve]

In my experience, Pagid are pretty much the default pad for Spec Boxster, and there are few if any complaints. Most SPB racers I know have gravitated to some combination of Yellow and/or Black (or even Red) depending on preference of feel and effective bias.

Given that you are talking about a few track days/hours per year, Orange will work. I ran them on my car when it was a street + track car for years (eventually switched to Yellow/Black for racing). They'll be noisier on the street than stock pads, but you'll get used to it. For HPDE, Orange is a reasonable choice. For a car that is driven on the street, Orange may be preferable to Yellow and Black due to less rotor wear and working better at lower temperatures.

My thoughts...

If you want a street pad that will also work for the track, then I'd recommend EBC Yellow. They won't make any noise on the street but may not hold up if you are truly running front of the pack Spec Boxster lap times. They are more affordable than Pagid. They might work well if you're only doing four track days per year and the rest of the driving is on the street.

If you want a track pad that will also work for the street, then as Trygve suggests, I'd also recommend Pagid Orange. That is what I currently run on my Spec Boxster that is driven on the street. The pads make some noise but they don't squeal like an 18-wheeler at every stop sign. These pads will provide great track performance but are more expensive.

To sum up:
Street friendly, affordable, good on the track: EBC Yellow
Great track performance, some noise on the street, but more expensive: Pagid Orange

As I mentioned in my original post, I've been using EBC Yellows, but found them to be terrible on the track. When they get hot, they cause a terrible juddering at each corner. Reading of other's experiences on this forum, I know that I'm not alone in experiencing that. They seem to work okay up to 7/10ths driving, but if you go past that, no thanks.

Sorry to hear that. I have gone through at least 10 sets of EBC Yellow and never had that experience (including racing 3 full season's on them). But I completely understand why you wouldn't want to use them again.

But for others reading this thread at a later date, they might want to give the EBC Yellows a try before jumping to a full race pad like the Pagid's.

I would agree.

I have been running EBC Yellows for a couple of seasons of tracking and not had any shuddering issues

[Racer Boy]

That's interesting. I wonder what the differences are in why they worked for you, but not me? I tried new rotors, and that made no difference. I also bedded them in according to EBC's directions.

In fact, I've tried green, red, and yellow EBCs; green faded easily (no surprise), and both reds and yellow gave me the shuddering. That's why I'm going to try something else.


Anyone here had experience with the Porterfield RS4s?

FWIW, rotor judder is generally from uneven hot pad transfer to the rotors. This is usually caused by failing to take a nice easy cool down lap or an easy drive down paddock row to cool the rotors down before stopping the car. I had this problem with Pagid Yellows and it got really bad but in hindsight, it was probably my cool down habits, not the pads fault. I cool down for at least 2 miles now and have never had another problem.

The best high heat pads I have used are Raybestos ST-43 custom cut from Porterfield. Excellent modulation, heat management, and they last 20+ track days. I have run these pads for about 7 years now and love them. Downside: They squeal like a school bus when cold.

Judder can also occur when you have two incompatible brake compounds on the same rotor. Ceramic and metallic compounds don't mix well and some metallics don't work well together either.

I switched to these brakes a week ago, in preparation for today's DE with PCA.

I gotta say, they're freaking AWESOME! Yes..... embarrassing on the street, what with the howl and squeal. But on the track, they're inspiring.

However:
I boiled the motul rbf600 fluid. Yeah..... I know.
Had to do a paddock bleed (thanks MaxD!). The next session I tried to brake harder, for less time. The brakes lasted, but I wasn't as smooth. I'll need to keep improving.

Ok so I have used the PFC 08s for a full season about 10 events.
Not going back to EBC Yellow. For one, wear is almost negligeable. The cold to hot performance also not a lot. Initial break bite a little less but modulation is excellent.
They cost almost twice as much but will likely last 4 times longer.
Also they are not.wearing the rotors down much.
They do squeal both hot and cold. Only drawback.

So PFC 08 it will be for.a.while...

[maytag]

I used EBC yellow last season for HPDE's. I had some mild shuddering when they'd start to get hot, but of more concern to me was the fade. Around lap 5 of each session the brakes would start to feel like wood. Very low initial bite and even less as I'd get into them deeper. I was always forced to take an "easy lap" to cool them off so they'd work again.

I'm running gt3 cooling "ducts" and motul rbf600 fluid. (Still rubber hoses, though)

Get pads with complimentary compounds and swap out the fronts when you put on the other set of wheels. So get some Pagid Orange for the front and rear and swap out to Yellow for the track on the fronts only. If you don't do a lot of track days - this works well.

[AZ986S]

I have an 02 S and I'm looking for track pads as well. My EBC yellows wear out very quickly, especially the front. I'm going to get a set of PFC 08s after a lot of deliberation. I now run in the DE4 groups and push the car a decent amount. How about the EBC oranges? I don't know about the others.

What seat and harness setup are you talking about?
I've read and re-read the thread... I don't see ANYTHING about a seat and harness.... this thread is about brake pads.

I have a Boxster non S 2004. I want to get new brake pads and new plain rotors. My car is mostly a street car and sometimes i use it as my daily driver. I'm planning next year to start to do two or three track days per year and have fun. Do some aggressive laps and cool laps but not anything like time attack or competition or unlike the OP 60 minutes of track time.

In my case will the EBC Yellows be fine or maybe get the Reds? I do not want a lot of squeal. I can tolerate a little bit of squeal but prefer no squeal. I will get the shim or damping plates my car do not have them, it has the stock pads. Was thinking of getting the Akebono pads for the street and maybe Yellows for the front but honestly i would prefer 1 set of pads.

If you want primarily a road pad that can take some extra heat then look at the Ferodo DS2500 or DS1.11
