rs4 brakes

[JAMES]

do the rs4 brakes bolt straight on to the s4,or does the s4 have a different offset/stud distance ect.
any info appreciated cheers

My understanding is the RS4 hub is the same as the S4 - I know because I have fabricated brackets to fit Porsche callipers. That means the disk and calliper will bolt straight up. However, you will need to check the offset of the disk ie the distance from the wheel contact face to the disc face. I did this once and I think it is the same as the S4. But if it does turn out to be different, you may get clearance problems with the calliper hitting the wheel spokes. Remember, the RS4 has much wider track because of the wheel offset and Audi may have moved the disc offset further out. Hope this helps. I am sure people have done this before. Anybody out there actually done this?

thanks for the info,by the way what porsche brakes are you using and where did you get thefabricated brackets.

I bought 6 pot Porsche 996 GT2 callipers from the US and fabricated brackets to fit them to RS6 discs. These discs suck so I will be getting 380mm Porsche ones when I get around to it. I also fabricated brackets for the Porsche 4 pot rear conversion using Boxter rear discs - major conversion! By the way, Dialynx will do this type of work for you.

i can get porsche calipers at a good price,do the porsche disks need modifying to fit,can the brackets be made to line up with the porsche disks.
were the rs6 disks the vented type(what was the problem).
sorry to ask so many questions but this seems a much more economical option for me and a lot of other people here.
whos the best person to speak to at dialynx.

The Porsche discs are bought without the bell. You need to have bells or hats made to fit the Audi hub.
The RS6 discs were cross drilled but the design is fundamentally flawed. Do a search on this site and you will find many comments on this subject. The cooling just does not work so they hot spot and warp. Also they are cracking around the vent holes. The holes are too small so they fill up with brake dust. At £300 each, you would expect better. Forget them - it is not an economical solution. Speak to Keith at Dialynx.
