It's design911 that had them for £500.

ETA - Pagid isn't available on Demon Tweeks, I checked.

Edited by J-P on Sunday 18th October 16:40

Always best to ring Tweeks and ask as they can get a lot of stock they don't advertise

OK I'll give them a call.

[J-P]

Ok got them for £421 - so a reasonable saving in the end. Most places offered them at just over £500 including Demon Tweeks. Should get them tomorrow.

Be interesting to hear how they compare..

(I could be wrong, but I understand you have to bed them in?)

You get the best out of any pad by bedding them in.

Will let you know. Yes they need bedding in and to be honest fk knows where I'm going to do it? 90mph to 50mph at medium pressure 3 times and then 110mph to 40mph with high pedal pressure 3 times. Hmmm... Tricky

I use a decent unlit quiet ish dual carriageway late of an evening. You can see the headlights miles off.

Track day or similar... don't bother with the 90 - 50 bit.... you'll know when they're done

[J-P]

I'd been thinking m-way or track day - the suppliers (who were excellent btw) said that as long as they were bedded in at some point, it's not an issue, so on that basis would prefer to do on a track day as I don't fancy travelling at licence losing speeds on the public road.

BTW - can anybody tell me why 110-40 is different than 70-0?

Because kinetic energy is proportional to Velocity squared. So braking from 110 you will be dissipating nearly 2 and half times the energy that you will from 70 - and hence be working the brakes correspondingly harder.

really ! I bet 50% of people here hit 100 mph on a daily basis.

And you need to do it straight away, pagid hate old pad dust on the disks and the way they perform is all about pad transfer into the disk.

Make sure you have jet washed your disks and drilled all your holds from old dust.

most people just fit them (esp dealers) and just moan a lot about noise and crap brakes,

I have run RS29 for 2 years and they are quite as a mouse with great bite over oem.

some people say only fit to new disks to get performance they were ment to do, but the guys in the USA swap out back and forth oem to pagid for tracks days !!

both seems crazy idea's.

from the pagid site and prob why the USA guys have brake fade lol

"MOUNTING NEW PADS ON USED DISCS (rotors)
We do not recommend using discs, which are pre-bedded, or have been used with friction material
other than PAGID. When Pagid race pads are installed on top of a layer of incompatible pad
material, bedding might take much longer or in worst case won‘t work at all. It can also result in
sub-optimal brake performance."

you know better than Pagid then ;-)

I have spoken to brake experts and race teams and it's a no no to use disks with other friction material on them, the whole point of Pagid taking the high temps is the material.

as disks are cheaper than the pads best to fit new disks really also no lip as the old disks will be lipped and pagids are not the same size.

But min drill all the holes jet wash the disk 1st if you don't want to buy new disks.

they are fussy pads and hence why we see so many people have issues with them and take them off !

[PorscheGT4]

you read on here time after time, poor brakes, noisy brakes squeal etc etc.

it takes 1 minute to put a drill though all the disk holes it's a no brainer to do it on £500 worth of pads.

Pagid can take the heat because of the material used hence the strict install use for best performance and pad infusion onto the disk.

why keep all the old st on the old disk for the sake of 1 minutes work per disk it could drop you temps by 100oc then we start getting the wapped disk posts all over again which normally is NOT a warped disk and just pad transfer.

I just think giving them the best start in life so they can reach 600oc £500 is a lot of money on pads.

if you have drilled holes like I have you see the hugh amount of old pad material come out, it's 1 minute to do it, a no brainer.

Cheers chap. It's all done now. Old brake dust removed and brushed clean. I polished the discs with an emery cloth to remove old pad patterns and any old pad material. Also chamfered the edges of the pads so that the pads bite properly onto the disc straight away and drilled holes in the rear pads, so the brake sensor works. All in all I'm quite happy with job (at least I know everything has been done properly). Now just need to think about the bedding in process and the job's a good'un.

ETA - in case it wasn't clear, I did stick a drill through the hole, tiny amount of effort. Doesn't matter whether it makes a difference or not, it's a no brainier to do it especially as I'd created more dust with the emery cloth.

Does anyone know the silver CR for sale at OPC Glasgow?

[Sarnie]

Been for sale for a while.............

Is that just the lack of buckets or is there more to it?

I nearly bought it but didn’t in the end. I've not seen it but i do know that the OPC has prep'd the car to a very high standard. From all the emails and images i received from the OPC i wouldn’t have any issue buying it if i wanted the R. I guess the normal seats, slightly high miles, rear wiper and maybe colour is the off putting factor.

Saw it today when looking around .I did not jump out at me it looks pretty bland in silver if I am honest and has no Buckets a must imo .Did have a rather nice GT4 in White just short of £100K .
