anyone here with a S2 Coupé and 312mm rs4 b5 rotors on the rear?

[Wolfgang]

hi,

as the title sais, i want to know if there is working conversion with rs4 b5 brake parts on the rear on the coupé quattro.

i´m planning to fix it this way:

RS4 B5 discs 312x22mm
girling 41/43 calipers
RS4 B5 brackets original

and find a fitting hub for that..

Maybe there are any other solutions with these discs yet? anybody able to give me some advices..

Thank you,

Wolfgang

I have all those parts, I have just never got around to putting them on.

Are they straight swap?

[Rocco]

i am not 100% sure but RS4 B5 rears are 300x22 true??

[Wolfgang]

hi Rocco,

NOPE! RS4 B5 312x22
S4 B6, this is what you mean: 300x22. This is the set that´s available on ebay..
RS4 B7 i think 322x22.

PS: is this the ceramic brake on your S2? is there a thread with fotos about it anywhere?

cheers

hi,

terry, do you think you can try things out concerning the rs4 b5 brake on the rear?

cheers

[terrybullwon]

not at the moment. Sorry

[Josh-stateside]

it probably would be somewhat of a straight swap if you dind't mind putting A4 rear hubs on the car. = +8mm offset. If you have 75mm rear wheel bearing the A4 hubs will work in the rear.

yes they are in

ceramic calipers + steel perforated discs not the creamic and hyper expensive ones


there are some pictures in my project thread :

it works.... ;-)

hi,

following components:

RS4 B5 brake discs
RS4 B5 brake-caliper brackets NOT modified
RS4 B5, S4 B5, A4 B5 Quattro rear wheel hubs
S2 coupe wheel bearing
S2 coupe rear wheel carrier
Girling 41/43 calipers

NOTHING on this components is modified, it´s a straight swap without problems!!!

The REAL BIG advantage is that you can use your orig. S2 handbrake cables, cause the handbrake on the girling 41/43 is the same way as it´s on the orig. girling 38 on the orig. S2 coupe.. it´s only a little bit more outwards..

pictures:

S2 hub left, rs4 hub on the right:



s2 coupe wheel carrier with s2 coupe hub orig. on the left, s2 coupe wheel carrier with rs4 hub on the right:



the rotor is exactly in the middle of the brake caliper carrier:







yeah!

best regards!

nice work

[Nuvo]

Well done solving this Wolfgang. Bolt on solutions are the preferred solution in my opinion.

[S2central.net]

Very good - swapping the hub is the only cure for the different disk offset. Great to know that makes it all bolt up nicely.
A for effort and A+ for following through !!!

[S2central.net]

Seksy looking disc by the way... and be interested to know if handling is altered much by additional track at the rear - it should give it a slightly wider stance and maybe improve grip at the rear. Let us know on that !

Wolfgang,

Well done, bolt on is best / handiest, and nice size at 312mm.

What cars does the 41/43 Caliper come on, is it just a B5 RS4 ?

Do you have a photo of the caliper fitted on the carrier / disc ?

Could I ask you for the part numbers you used for the disc, caliper and carrier ?

Thanks again for sharing.

Kind regards.
