EBC Yellowstuff (4000 series) installed on all four corners.

I broke these in the evening that I had them installed, but after about 150 miles of driving around town and the highway, I think they're 93-94% broken in.

There is definitely some extra bite there, I can tell because braking now feels effortless and I'm having even more difficulty telling how fast I'm going and you could say I'm getting more braking with less pedal travel.

These brakes do need to be warmed up a bit before peak grip is reached, but they warm up pretty quick. The car feels much more stable and planted during straight line braking, although I've managed to loosen up the rear a bit more during trail braking.

All in all, I think it was worth the upgrade. I'll check back in 350 miles more and then at 1000 miles.

 

Small addendum: they are quite squeaky and I'm not sure if that's just normal OR if I should be concerned.

Does anyone have advice?

 

EBC Yellows are known to squeal until they are fully broken in (roughly 500 miles street driving), also be aware that these are really dusty pads. Make sure to clean your wheels regularly especially in warmer weather. Don't want brake dust baked on.

 

After using these extensively over the last 4,000 or 5,000 miles, I had some trouble distinguishing them from the OEM Pads.

There was a noticeable difference in bite, but I believe that the stock rotors could not sustain the higher optimal breaking temperatures that the EBC Yellows are designed for.

My discs are torn up. After 5 or 6 highway-speed stops down to 30-40 miles per hour, there is definitely break fade.

If anyone else had a similar experience, please let me know.

Thanks,

 

I ran these at a couple of track days recently .... On the street they are not very good because they take some warming up . Several times I have almost got caught out when the brakes were cold and had to make a quick stop .
On the track they felt ok and seemed to be handling the punishment, but I pulled them out today and they appear to be falling to bits .

Admittedly I received these pads second hand but still ..............not impressed !

 

Tried them once (yellow "truck" pad for tow vehicles), never again ...

I'd actually recommend Centric semi-metallic pads from RockAuto etc as a better lower cost pad than EBC ... or the name brand semi-metallics if you are wary of Centric.

 

Yellowstuff are supposed to be dual purpose street/track pad ?

 

According to them, yes. Yet EBC also claims they won't fade, need warmup, or damage rotor surfaces ...

Yellowstuff Fastest Street, Trackday & Drift racing brake pads

IMO they all seem to be brownstuff, but maybe I'm just color blind

 

I have been interested in these pads in the past, so your comments are interesting to me.

Concerning the squeal, did you apply grease to the appropriate areas when you installed them?

Did you break them in exactly according to EBC's recommendations?

If I am reading this right, you are saying you have trouble getting them hot enough, and they are easy to overheat resulting in fade? Yikes. That means they excel at neither the street nor the track, which is quite an indictment.

BTW, The stock rotors are actually quite good. Short of spending big money on a BBK, the stock rotors are hard to beat in the aftermarket.

 

No direct experience here, but a guy I know had them on his R32 GTR at the track and when driven hard, they'd experience pad fade quite badly. So I wouldn't be inclined to use them. On the other hand, the RX8 has bigger brakes and less power, so it might be ok.

 

I'll try to do some recon at the track tomorrow and see what I can find out from guys using these pads--assuming anyone actually is.

 

Well, that was easy. They held combined classroom sessions with intermediate and advanced groups yesterday, so I just asked the question during class. The emphatic unanimous answer was, "waste of money, fade when hot, might be good for light trucks." So, these have been scratched off my list.

 

Not even for that ...

 

Junk as junk gets. Project Mu pads FTW.

 

so what is the HPDE track/weekend spirited drive pad of choice these days

 

I'm quite happy with Hawk DTC-60's so far and they're even pretty reasonable for the drive to and from the track. Much better all around than the Porterfield R4 that I ran on my FC.

 

How are those DTC-60s for noise?

I am running DTC-30s and like the amount of torque with the tires I run, but they have started howling almost as badly as HP+.

 

Just bought DTC60s for front and 30s for rear . Fingers crossed for this weekend on track !

 

I have been using Project mu HC+ for over 6 years now and they perform well at the track and road. The down side is the dust and rotor wear.

 

DTC30 rear for asphalt track? I didn't care for them on autox rear many years ago, you need a better pad to match the DTC60 fronts IMO ...

 

Didn't want the 60s on the rear because the rears were locking up first when i had the yellowstuffs at both ends . (wilwood 4 pot on front and stock rear calipers)
I was just going by the friction/heat charts which showed them running parallel up to the point the 30s gave up . Didn't get a chance to try them over the weekend unfortunately.

 

You went too far in the wrong direction. They fall off too early and too much at high temps

 

They are supposedly able to handle more than Hawk blues which is what all the rx8 race cars here use .... so i figured I wouldn't get them that hot ...


What would you have chosen in my case ?
.......

 

I have EBC Yellows as well, I do find they aren't really up to the task of a track day. Aside from the dust I actually like them for autocross, though. They have good bite cold, and I like the pedal characteristics.

Still probably gonna try an HP+ or similar afterwards, because they don't cut it on the track and are expensive.

 

At first they were very quiet, but after track use they got noisier. At worst, they're maybe equal to an HP+ for noise, so really, not too bad for an all out track pad.

I'm using them front and rear and haven't had any issues with bias.
