DS 1.11 bedding in

I found that the DS1:11 didn’t make much noise at all on the street or even after track use. They created very little dust and worked well from cold also. I think you’ll like how they feel on track; very good release and modulation. Keep a check on wear after 1/2 pad life as mine went very quickly!

That's good to hear, thanks. I tend to bin pads quite quickly past the half point as too thin a pad seems to disproportionaly affect heat dissipation so it becomes quite easy to cook a thin pad, however resilient it inherently is (the M2 is heavy too) so it becomes a false economy. They're only very cheap at almost half the cost of RS29. I have Snet early September to test them but first impressions are very good indeed compared to the OE pad, it seems that I have zero dead travel but that might be due to the thicker pads as the fluid level has gone up a bit. Modulation is indeed very good so far but I need to recalibrate as the set up now feels a little over servoed, but I am sure it's simply down to the higher friction coefficient. I haven't put the RBF600 in yet but will do before Snet as this could be the next weak point (before the seals lol).

Enjoy Snetterton and post up your review afterwards!
I run them on a TTRS (which is also reasonably heavy) and get two full days out of the DS 1:11 whereas I got 3 days on the Pagid RSL29. Still prefer the Ferodo.

That doesn't sound like a lot of longevity but then again maybe you do a lot of laps per day.

I really like Snet, it's in my top 5. It's got a bit of everything and when possible I short shift the back straight and use it as a brake cooling section.

It isn’t a lot of longevity but the car weighs 1390kg and with AP racing 6 pots and Nankang AR1’s I’m seeing -1.4g in heavy braking zones which takes its toll on the pads! I’ll usually drive around 60 laps per day.

Those APs are beautiful and probably the best part of £3k per axle I guess? I am not sure my engine would cope with 1.4g what with oil starvation.

Yep, a bit over 3k for the front...I initially put on the AP rotors and ran with Pagid rsl29’s as I thought my 8 pot Brembos that came on the car would be ok. I was wrong and ended up adding the AP pro5000 calipers which are amazing! (I also saved over 15kg of unsprung weight over the oem setup which made a huge difference).
I’ve haven’t driven Snetterton yet (it’s a hike from North Yorkshire) but did visit the circuit last year to watch some racing...looks to be a great track; hard on brakes?

I would say medium. I could get 7/8 decent laps in the Meganes out of simple PFC Z which are road pads with a slight track bias.

2 big stops at Montreal and Agostini. They're quite close so if you've made it past Agostini then you're OK as the rest if flowy.

Brundle/Nelson can be a bit taxing too but they come after the long back straight and you can sort of "spread the work" between the two.

If you've never been, I would encourage you to try it despite the distance. I guess you're 3/4 hours away which is similar to me in Sussex.

I'll be there on 09/09 with Javelin.

[NardoRS]

Probably not this year as I’ll stick closer to home (Croft, Cadwell and Donington) but it’s on the list of must drive circuits!
Enjoy your track day Nick!

[nickfrog]

Cheers. Cadwell is on my list of new tracks to try this year. Looks a bit daunting in places... Is it that bad / scary?

Cadwell is fantastic. I live 30 mins from Snetterton and I’ve been to Cadwell 8 times in the last 12 months-it’s brilliant!

One of the great things about it is it’s rewarding whatever your pace. If you just want to take it easy you can treat it like your favourite road but commit 100% and it just comes alive. It’s beautiful too, really scenic if that’s your thing.

Just be aware that fuel is only available 3 times a day so there’s often a queue.

[NardoRS]

I’ve only been once but it is a very rewarding and technical track; great scenery too! It is narrow which adds to the excitement.

Your car sounds incredible!!

Thanks! ...one a the top reasons I went for the TTRS is the 5 cylinder motor.

Yes I am on the basic blue 4 pots which offers a much better choice of pads. The Ferodo ref is FCP4611W. I bought them from Tegiwa with discount code Forum25. https://www.tegiwaimports.com/ferodo-fcp4611w.html

They were very easy to fit, you just need the right size punch for the 2 pins.

They rattle a little bit as they don't have the anti-rattle "ears" of the OE pads but you can only hear it at low speed and even then it's very muted.

No squeal so far but I haven't bedded them in yet, just normal road use.

hi Nickfrog,

About to bed in my DS1.11 on the M2 and wondered if you had anything to share on your experience? Reading this I am off out this eve to find some fast quiet roads to do some hard(ish) stops. THen off to Donnington tomorrow eve.

They have proven to be the ideal pad for me on this car. They're not supposed to be as good as the RS29 which are 50% more expensive but in fairness they've been great so far. Have a great time at Donny.

[dufflecoat]

Thanks fella, well mine are now "bedded in" I think!

A good run getting them up to temp, then about a dozen or so hardish stops followed by a long cool down and now left overnight. See how it behaves tomorrow.

IIRC you aren't actually supposed to stop.

60 - 10/20 a few times, drive to cool down & repeat.

[iguana]

Suprised if you don't get road squeal, great pads, but do squeal like a piggy on my track e36 when used on road.

Correct, sorry, I didn't "stop" just slowed as you described.

I figure the important bits are

1) getting them to temp
2) Adhering materials at right temps
3) Letting them cool before you stop
4) Leaving them to properly cool for as long as you can

Ill report back on whether I f*&ked them up or not

[dufflecoat]

to update for those that will be reasrching this in future.

The bedding in "process" above worked for what its worth.

Took it to Donnington last Weds for 3 x 20 min stints, and done a 100 or so miles on road with them now. Observations are:

1) These with HEL lines and SRF on track I suffered zero fade (as expected on such short stints anyway)
2) Stopping power is great, I need to "re-learn" by braking technique and braking points as was ending way too early and coasting into apexes. Good for the future I guess as gives me much more room.
3) On road they squeal the odd time, very slightly on final approach and its not too loud. Easily manageable with slightly modified road driving.

Overall, a great choice. Lets see how many laps they last me once I work out how to use them
