Guys I have Green stuff Pads and Rotors on my 325 its a properly preped track car running wit hall the goodies - we drive it as hard as we can should I be replacing the Green stuff pads with Yellow or stay as I am or try a different pad entirely?

Does it stop ok?

Track car only? I reckon the Yellowstuff a better pad.

Tar-ox corsa pads for me with either g88 disc's or red dot eqivelent disc.

Greens are shite.. Yellows, or Performance friction

+1 but I haven't tried performance friction so I cant comment on them.

Running PF's on mine..

Hmm i've been told Pagid RS 29s are the daddys - at £141 per set they should be tho !!! any expereiences?

Running Yellows on mine and very happy with them.

1: Pagid RS 29's
2: Mintex 1166's
3: Ferrodo 2500/3000

Any of the above would be an "upgrade" IMO.

I run pagids and love them, moved to them from Mintex. Ferodo also very good.

Yellows have the same, if not better, bite from cold as oem pads.
They're no noisier and I couldn't get mine to fade on the 'ring.

Pagids are the next level, but then they're almost £100/set more expensive.

Assuming you run standard calipers, how much are the PF's?

Rs29's for racers with an open cheque book. Almost without doubt some of the best pads about.

Yellows for trackdayers with a budget conscious mind set. The only thing I have found is that they crumble slightly, but rs29s will do this as well, but perhaps not to the same level.

my yellows fell apart and wore out faster than a stock pad, poor show all round then again it was in a heavy m52b28 powered car

My yellows have been fine in the S50, and a heavy MR2 before that. They crumble on the outer 2 or 3 mm at most, but have been fine.

Even with hard disks (barely even a groove after 3 track days), I wonder if having the wilwoods makes any difference.

Perhaps they were a bad batch or an older compound?

ordered the yellows, depending on how they do will maybe try the Pagids next season

thing is how hard do you brake- would love to go up against some E30s to see how late you can leave it- otherwise its difficult to know where you stand?

as hard as I can before the back end starts snaking really, but I could do with better brakes, especially on the rear.

I would also prefer setting up by bias and have a proportional valve too.

RS29s for me, heard too many horror stories about EBC.

I have used EBC Yellows on my track car for a while now and they have been very good indeed in terms of fade resistance and modulation.. I would have to disagree on the "bite from cold" though as I feel they really need a little warmth in them to give of their best.

However, others here rate the RS29s and Perfomrance Friction's offerings very highly indeed. Have a read here:

I have yellow stuff pads all round and ebc front discs on my track car, it pulls up really well and the last ones lasted for ages too!

I would tend to agree. I suspect the bite from cold feels good as when people change the pads to something performance orientated, they usually change the discs and check the caliper mechanisms and refresh where neccessary. So they are comparing potentially worn out products with new ones.

Interestingly I found that the initial bite from cold when I first fitted the pads was quite good, but having put some hard track miles and a LOT of heat cycles on them, they seem distinctly worse from cold than I remember. This could be the bedding in friction material having a different compound property or just randomness. Alas it doesn't bother me as I am only worried about high temperature operation.

Yes! I've noticed that too - they do feel worse from cold after you've used them on a trackday or two but as you say, high temp operation is where the priority lies for a track car. Yellows do have a brake in coating, so perhaps that's why.

I always need to give Yellows a lap to warm up before really standing on them..

I agree with both of you there, they are great from cold when only used on the road, but need a damn good push when cold untill they have worn off a bit. I think they get a little glaze on them which dissapears again with heat and/or time.

mine are pretty awfull from cold now too.

need to change em for something with really good bite from cold, but don't need to worry about heat resistance as will be used for a hil climb, wont get warm enough in 60 seconds.

any idea's?

Pagid.

Rs29's are endurance pads, they last longer, thats why they are more expensive, we've run a whole season's racing and also about the equivilant of 2 season's trackdays on our set, and they have still got plenty of meat on them!

+1 for Performance Friction. E30 Pads are only available in 01 or 06 compound. I would recommend 01, I use 06 but that's a personal choice.

What's the difference between the two compounds?
I'm kinda glad you posted this as I was going to ask if PF did a regular range as well as a performance range of pads.

Well i put the yellows on and discovered that the old ones were yellows too- Went to Rockingham this weekend and due to rain in the morning had chance to bed them in gently then in the afternoon i really stood on them and they were fine even after 4 hot laps you can still lock the front up if you want
incidently does anyone have a "good" laptime for rockingham?

RS29's are excellent. They lasted 7 track days/races for us, so about £25 each outing.

I am trying the Mintex FR2's this time, slightly cheaper but I want to experiment.

For the 1.7M circuit, your car did it in 2.04.52 back in 2005 if that helps...but it was capable of better as I was gaining on him using a bog standard 325 engine on standard injection through the twisty bits and he pulled away again as soon as we got to the banking!

01 is slightly more aggressive, and bits from colder. 01 is PF's traditional race compound for the front. 06 is their newer 'enduro' compound, slightly less bite, longer pad life, requires more stable temperature environment (i.e. don't use for night races or street where they won't get hot enough). That said, I prefer 06 as it offers better value in terms of pad wear, and is not too aggressive for a semi-slick tyre. With 01 you really want a full slick tyre, unless you had plenty more mechanical and/or aerodynamic grip.

Performance Friction do 2 street pads, Carbon Metallic and Z-Rated Carbon Metallic. Whilst they used to make the E30 front pad (0278.xx) with street compounds, they now only do race pads. Shame, as their Z-Rated is pretty much the best out there; low dust, low noise, high heat tolerance (for street pad), excellent bite, consistent performance, and easy on discs. It is available for most later BMW pad shapes though...

So basically unless it's a track car I'm stuffed?

Yes. You are stuffed, n00b!

Though I am visiting the Performance Friction Brakes factory in Clover, SC, this week or next week, so will relay to them vigorously that there is possibly demand for a batch of 0278 pads in Z-Rated, and possibly 0279's as well... So long as you're willing to order 100 sets, they've got no problem doing it for you!
