RS4 front brakes on pre facelift S4? Is it possible?

[rosshyslop]

Yes the B6 S4 calipers fit straight on to the B5 with no problems.

so the next question is do the front discs from a B6 S4 go straight onto a B5? Im hoping they will give better performance than my B5 setup without the expense of RS4 discs!

[craigg]

yes they do. and they should fit under the standard B5 wheels too

Disks are available from motorfactors for around 80quid a pair, which is significantly better than the £lots the RS4 disks cost!

In the case of RS4 disks, its probably cheaper to get a set of wilwood (or similar) bells and rotors made up to fit. Rally design do universal bells for about 60quid each (just need skimmed down to the exact size required) and 355mm disks to fit said bells for 140ish each. should work out a little bit cheaper than a set of RS4 disks the first time round, and more so for subsequent times...

You might even be able to find an aftermarket supplier who do rotors that will fit the audi RS4 bells.

Do the rear Rs4 B7 brakes also fit on a S4/A4 B5 quattro?

Anyone want to sell their stock B5 calipers and carriers?
