Expensive vs cheaper brake disks?
Discussion
Just looking for new front disks for a mate's 997 911. He's been quoted a lot by Porsche, but on eBay cheap disks can be had for as little as £99/pair.
Obviously this isn't an area to scrimp on, but what is the *real* difference between a set of Porsche disks versus more expensive 3rd party disks versus the eBay £99 specials? My cynical mind wants to think that they're all just hunks of similar metal machined to the correct size, and that Porsche could well source their OEM parts from the same factory anyway?
Metal quality? Wear rates? Warping?

Don't do it.
They are not the same.
If you were talking about a 80hp shopping car I might be tempted, but not a 997.
Don't worry - it's not going to happen. We're just interested in what the actual difference is They are not the same.

See here for an interesting example: Porsche discs for £155 each, or 'OEM quality' for £60 each.

Does going to a 'known' 3rd party supplier --Mintex, or EBC, for example-- matter?

Don't think so, never had any problems.A few years ago the OH had a Pug 406 Coupe 3.0 V6 which had Brembo (or Bimbo as she liked to call them) brakes.
Pug wanted £439 for a pair of front discs. So I turtled off to Brakes International and got some there for £70. Bloke goes off into the back, comes back and plonks two big red Brembo boxes onto the counter in front of me. So I personally would avoid your main dealer for them.
Just my 2p.

Buy cheap buy twice! Ive learnt my lesson when trying cheaper pads/discs.As already said if its a shopping hatchback then ok but on a performance car you get what you pay for.Ive had everything from disc judder to unbelievable pad squeal(mintex) when trying to save a few quid and in the end it has only cost me more.
Unless a reliable source can confirm to you that THOSE discs are absolutley fine on THAT car i would be very carefull.

I've seen first hand the engineering that goes into a disk capable of stopping a 200mph car weighing 2.5 tons and the consequences of an aftermarket disc. It's not worth it.
The devil is in the detail, the machining, stress relief, radii in the castings, balance, porosity, and last but far from least the material composition.
Same comments apply for the pads and the clips/sticky pads required to fit them.
