Question is are those ridged, or is it a surface pattern as a result of the x-drilling/hot gasses from the holes. Only way to be sure is to get the OP to run his finger over them.
Got a chance of a C55, what do you chaps think....

Hmmmm
Just checked my other car which has three month old cross drilled grooved and vented discs all round. Same pattern as the op has and I have on my C55.

im not saying there worn out! they may still be in tolerance but they are wear marks merc will have a set limit as to how deep them ridges can be! and if for instance they were close and you had say 2mm left on your pads then you would fit new discs as they may not last the life of a new set of pads!My front discs looked pretty similar to the OPs photo - and I was told they had loads of life left in them...certainly stopped well enough

Guys,Just as a follow up to this...decided to stick with the TT. Felt it was a better all rounder and more fun.
Cheers for the input though.

Yes they look flat - a "pattern" is visible, presumably related to the holes allowing the gasses to leave the surface of the pad and changing the pad/disk interface behind the hole. May not change the were characteristics significantly, but enough to show a pattern onf the surface.The brake disks don't look right, here is an image of mine and they feel/look flat

Excellent choice, you wont be disappointed. All you need to do when you get it is to go and find a standard 911 or suburu type thing and embarass him/her

Take a deep breath Andy.
Now, what you see is a pattern...not ridges. The pattern is caused by the holes. The pattern will not effect the characteristics of the discs one iota.
Will you quit with all the loling. It's not funny.

he says when he runs his fingers over the face they are un even! this is wear not caused by the holes iver as normal discs can wear like that too now i havent said they are worn out as there will be a set tolerance for how deep the ridges can be set by the makers of the discs! can some of you guys please wright to nor breams the people who make alot of discs for people like merc scania and daf as if they are wrong and wear like that is always going to be ok then ive changed a lot of discs at work for no reason going by there guide lines lol
