So I'm going to need new front discs soon and I know the Pheaton discs are the exact same size as the RS4's but a lot, lot cheaper, question is are they worth it?

I'm thinking it'd be possible to drill the Pheaton discs too using the old RS4 one as a template and countersink the holes slightly. I know you have to remove the actual disc from the hub part and use the existing Audi hub.

RS4 discs are around £550 on eBay for genuine Audi ones.

Phaeton discs are around £250?

I'm not on a budget as such but I'm not paying £300 extra because it has an Audi stamp on it!

Thanks

dont even think about drilling the discs!

Do the phaetons defo fit

Anyone here done it

Or know of any threads?

I put phaeton rears on my old RS 6

I definitely wouldn't drill the discs! It's done in a factory with exact prescision. I would imagine the phaeton discs would not perform as well under pressure due to lack of cooling from not having holes. I wasn't aware that they were the same size but I guess if they fit and you're not too particular about braking performance then give it a try. I don't think I would.

They will be perfectly good enough for road use

The phaeton is a big heavy beast and in W12 450ps I would imagine requires some pretty decent brakes!

Maybe on a track the cooling from the holes will help

yes they fit but you have to swap the bells over as the phaeton has lore of an offset. i kew someone with them on an rs6 and he didnt have any problems,. dont get them drilled you will weaken them, you could however get them grooved

I have searched about doing this and it had been done a lot , all you need to do is get the pheaton discs and swap them onto the rs4 bells , you can even use the brand new bolts and washers from the phaeton discs and that's it. A guy off here told me about it and said that some are using them on track and they are fine

I think the holes in the RS4 disc are more about looks than function. Agree 100% with the groove though.

three things i may have learned the hardway:
1. dont purchase cheap tyres
2. dont EVER skimp on brakes
3. dont pee into the wind

I dont know Pheaton, would love to have some first hand opinions on them
