D3 S8 Ceramic Brake Backing Plates
 

Howdy all,

I've just had to purchase a brake disc backing plate for my S8. because it has the ceramic brakes, the backing plates are horribly expensive (£300+). If I'd known that, I wouldn't have tossed the old one away so carelessly!

While checking the car, I noticed that the front driver's side backing plate on my car seems different from the others. Where all the others curve over the disc to protect the edges, the OSF backing plate curves away from the disc, leaving the edges exposed. :Confused:

Could someone with ceramic brakes tell me if it's the same on theirs? I'd hate to have to buy another one of these infernal things!

I noticed the same thing on cars at the German meet and the only thing I could conclude was that they had been fitted back to front.

I don't know, but looks like one SKU covers left and right - so it will be as you say curving over one side and away on the other.

Are there any merits in swapping to the Phaeton cover plates with the air duct?

I know that a few of the D3 Owners in Germany who we have seen at German Meets have done this mod +++

Straight bolt on parts as well. Not that I suffer from overheating discs as I don't drive hard, but something to think about +++

I'm just wondering if they do it deliberately so that the discs get more ventilation??

Easy enough to fit. One backing plate for each side (3D0615311C & 312C), one air guide/duct for each side (3D0615447D & 448D), and 6 bolts each side to secure it (4x N10065002 & 8x 90842903)

Total for the parts from VW main dealer is £157.xx (no cheaper through TPS).

Not a bad price for new parts and an hours DIY time to fit +++

I'm confused. I don't get why one would not be a protective as the others, unless it is, as Del has suggested, fitted backwards.

Do all of your backing plates cover the disc edges?
