Dear All

Not sure whether its silly season/ motor factors encouraging us to spend our hard earned money......

I've been meaning to change my front discs for sometime - in the past I've seen these (928 S4 part M030 as per 968 which is handed) at about £90/ £100 per disc for standard non-cross drilled.

GSF are offering these at £50.40 each, Eurocarparts (Pagid) @ £61 each. Looks like the rears and standard (e.g. 220 turbo & S2) are also cheap as chips !
 
After the issues some friends and I have had with the 'OE' stuff from GSF I would be tempted to shop elsewhere. In my case the discs were out of spec by the second pad change (I guess that can be expected) but Brembo and Bendix pads seem to go off colour within a few thosand miles of being fitted ; the cheap and nasty pads I got from Motor Factors Direct were far superior (yes, the fading had become that bad!). I would have said it was a one off or me, but for sets of pads to do the same thing is quite a coincidence and for the same to happen with a friend's Clio 172.

Small wonder a local garage told me to go either with ECP's priciest pads (well, best pads) or genuine on both discs and pads.
 
Car parts for less on ebay are even cheaper

Sebro ones as well under £50

400744166849 eBay item number

Part number is 928 as well.

Iv got m030 type may buy some now if there right

 
I would recommend Pagid pads (available from ECP and other Factors) They even survived well on my track day car.
 
I about to remove and send back my second set of pagid discs ( front ) as they keep warping.

I'd politely suggest that its probably not the discs themselves but a combination of the pads you're running and/or lack of appropriate cooling to the discs.

IMH experience, you've got to get discs stupidly hot for a period of time to actually warp them. Uneveness or the feeling of warping is usually a function of material left on the disc or the discs not sitting flush on the hubs.

The discs I do not know about (I would guess that they are ATE or Sebro) but the pads are Textar via the dealer:).
 
As Chris has suggested: discs don't often, if ever, warp. Most brake problems are attributed to 'warped discs' though.

I agree Chris. However the padgid discs that Euro supplied are not good quality. As soon as I changed them the vibration disapeared. I am using good quality pads , I haven't over heated them and I know how to fit discs and pads. When I took them off I put them on the lathe and checked them, they were like an old lp that had been left in the sun.
 
Don't forget to use a clock gauge to ensure the discs are fitted within the manufacturers tolerance for lateral run out, 0.1mm I think for a 944 turbo 220bhp.

If they have excessive run out then every time the high spot passes through the pads it gets a slight shave. Over a couple of hundred miles the shaved areas thickness reduces to the extent that when you apply the brakes you feel judder as the disc of now varying thickness passes through the clamped on pads.

I had this happen after an indie fitted new discs. I remounted the discs within run out tolerance and 200 hundred miles later the the thickness wore back to even, no more judder.

I fit my own discs all the time now as I have not found a garage where the proprietor does not look at at me in a funny way when i ask him to clock the discs after fitment.
 
I'll put a clock on them when I refit them. I've used the clocks to check them before I took them off but I've never done it when fitting them.
