Not really seeing much on the difference between the 2 pads . Can anyone here provide some input ?

Going to step up from the DS2500s probably this season and trying to figure out which one I should go to .

 

I’ve been using 1.11 for about 6 years. Various cars, 997.2 rs, gt4, 992 gt3, street and Hoosiers. It’s a fine pad. Flat and Linear temp/friction curve, sparks great at low and freezing temps, they last a long time, and they are very easy on rotors. Down sides are that it’s friction coefficient is lower that a sprint pad, which I’ve not have any trouble with but some people like a really strong initial bite. 3.12 and 1.11 are similar in their temp/friction curve, but the 3.12 has much higher friction, and a stronger initial bite. I hear it also is less noisy on the street. It’s has slightly worse longevity and rotor wear. All in all, it’s a better pad I hear. I plan to try it next - primarily for the lower noise on the street. Most gt cars have plenty of brakes, I don’t feel like I need more. Compared to the 2500 both pads will seem superior in every way, even on the street. The 2500s have a dangerous minimum operating temp.

 

Never tried the 1.11 but I've been running the 3.12 for about 6 months. I love them. I believe Ferodo quotes that they don't fade and they don't. I ran at COTA today and while my tires were starting to go off toward the end of the day, the brakes were still great. I used to run Pagid Yellows at recommendation of a shop and I found that by mid-afternoon I had to break a lot earlier (225 mark instead of 175 mark) by mid-afternoon. I even called Pagid because the pads had a lot of life left (well in depth). They said that because COTA is a very hard track on pads (all 3 straights are into very tight turns therefore hard braking) you can't expect the pads to last. Well, at least not *those* pads. Now the one downside - the Pagids are streetable as are Ferodo DS2500 but the DS 3.12 is very close to a race only pad. They claim as such. The downsides apparently are:

- could wear out rotors much more quickly on the street
- cold brakes don't stop

I found the latter out immediately - first few times driving on the street I had to warm them up by repeated braking just to be able to brake at all on the street. Since my car is mostly used to drive to/from the track and of course on the track (or carving twisties) I felt that this is a reasonable compromise. Since I don't do stop-n-go driving or commute in this car, the 3.12 is an ok compromise for the street to be able to drive to the track.

Unfortunately I know nothing about the 1.11 but I used to have the DS2500 on my Lotus and I hated them. They claim its a street/track pad but when I used them I was getting ABS to kick in way earlier because the car was not stopping (well) on the track. I think they are probably fine for a novice or low intermediate track driver but anyone more experienced would want something a bit more aggressive.

@ANGST I've used both at our home track. For me, on our cars, the initial bite of the 3.12 was insane (took a bit of getting used to) and they just did not fade. The 1.11s on the other hand were much more linear (easier to trail, again for me) but didn't have the same initial bite nor heat management qualities. I ultimately preferred the 3.12, both however are a huge step up from a street pad.

 

Didn't one replace the other?

I used to run the 1.11's and now it's all 3.12's, or do I have that backwards?

Regardless, I love them both. The 3.12's have great initial bite, no fade, and some really decent longevity.

I do notice that they go from 100% to 50% much slower than 50% to 0%, but I think that's true with every pad.

Angst, you can't go wrong with the Ferodo's. Either one of the two you mentioned will be better on the track than the 2500's.

I am PRETTY sure I put 1.11s in your car

Most vendors offer both still , so I don't know .

I do drive my car to the track , within about a 4 /5 hour radius . I have heard that both 1.11 and 3.12 are streetable , and not , depending on who is posting .

 

1.11 are most definitely street-able. They bite right away, even when frozen. Noise is the only issue.

 

Before I trailered my cars to the track, I streeted the Ferrodo's to the track no problem. Shouldn't be an issue for you.

 

DS1.11 is very much alive. Have found some GT4 guys like DS3.12 up front and DS1.11 in the rear due to less initial bite. All the 991 GT3s like DS3.12 front and rear.

 

I ran DS1.11s for a season and then DS3.12s for a season. I found the DS3.12s are a little too torquey for my liking on street tires (Yoko A052s). They made threshold braking while avoiding ABS trickier and the car more likely to lock up wheels in bumpy braking zones. I found the DS1.11 squeal "normal" and the DS3.12 squeal absolutely insane. If I go with Ferodo's again, I'll go back to the DS1.11s. If you're running R7s or stickier, DS3.12s are likely the way to go.

 

Sorry I don't have a back to back 11.1 and 3.12 comparison, but on my street/track 996 on 200TW tires...

• Use 2500 for my normal street pads. They're fine, but don't have great cold torque.
• Swap to 11.1 the night before a track weekend. Even less cold torque than 2500 but are manageable, they have elevated noise (but that's part of the game), provide excellent braking on track, and don't overpower 200TW tires.

 

We have two customers using 2500's on their 718 GT4's and at least one of them is running very smooth 2:04 laps on VIR full which is a pretty respectful number for a stock GT4. However, this winter he is going to a wider tire so he is upgrading to DS1.11's F/R. We will report back with how he likes them! The 2500 is really a street pad, but it does well for beginner and intermediate use on lighter cars.

Most GT3 customers go straight to the DS3.12. Having driven a 991.2 RS with the 3.12's I don't think I'd want to go down do the DS1.11, I was very confident at 165 MPH at the end of the backstretch at VIR with the 3.12's.

Did I meet you over at Quantum late October? I spoke with someone there and he gave me his card for KNS Brakes.

Viper Green GT3.

Was that you?

 

Yes! That was most likely Ken.

Yup, that be him. Tried very hard to sell me different rotors and different pads. Quite the sales pitch, but I stuck with the Ferrodo's and Gyrodiscs....\

Maybe next trip in March with HOD and Chin March 3-6...

Carry on........
