brake conversions info Required

[micky]

Right I have a few questions so bare with me

I have a Audi 80 Quattro b4 with 4x108 stud pattern
Hopefully I will soon get some rs2 brembo callipers and I need some disks
how can I upgrade the brakes to use bigger disks?


1st Do I get an A8 disk 314x30 5x112 and hope I can find one with just 5 holes and not the usual 10 .so I can drill another 4 holes to 4x108

2nd do I use a ford disk which is 4x108 but the middle needs opening and the dia needs shortening.
Where can I get them machined if I need to do either .

does anybody know if the s2 5x112 hubs will fit straight onto a 80 b4 ?

or anybody managed to do a conversion with out using all s2 parts .

any info would be great .i hope to get some replys even if they say i am mad

5x112 conversion can be done without using any S2 parts.
What to use depends on wheel bearing size on the front and rear axle - fwd or quattro.

Anybody know the overall size disk dia on a rs2 disk

I think rs2 is 314mm diameter but someone should confirm

Yes, 24 is thickness in mm.

Didn't see were it stated in ETKA that has to be this or another combination ...
You want to say that can't be 304/299 or 322/290

[Val]

Larger brakes are for "modified vehicles" - that's written in etka.

Don't think manufacturer would modify front brakes and leave rears intact...

[sailaz]

you are no right. and example with a frog - useless



and mine has 304/299 and confirmed with VIN at Audi dealer.

P.S> I was thinking what for such choice and only one reason came to my mind - to use smaller wheels ...
