RS6 front brakes onto RS4 B5

I guess no one here has a measuring tool?

I guess no one here has a measuring tool?

I've just gone out and bought one - I measured 2567854678 microns!

Actually, I measured around 24mm, that's with new pads (less than 2k miles)

ask the user on the forum that removed the movits and replaced with rs6 setup

Thanks Doug!!

Hi Ash,

I had the Movit 4 pot setup on my RS4 with 380x32 discs. The brakes can only be described as stonking. They hauled the car up from phenomenal speeds very quickly....made my eyes bleed.

But as you may have guessed there was a downside. The first set of discs lasted about 9000 miles before cracking and failing an MoT. They also suffered severe vibration.

The second set of discs lasted about 6000 miles before the inner surfaces wore out. The outer faces were perfect..the inner surfaces shot. I decided that I'd prefer the more cost effective option of the RS6+ setup compared with the regular replacement of the Movit discs and also I could get replacement pads very easily from VAG Parts, MRC or my local stealership.

For me the choice was one based on cost. If money was not considered then the Movits provide more braking power.

HTH

I just want better brakes than it has as OE (which are very unimpressive I have to say) - it would be really nice to have the movits, given they sound phenomenal, but does dsound a little excessive (although I am a low mileage driver, prob <5k pa so wouldnt be too bad)

So, the B7/rs6 setup got fitted today by Kim collins and he's finishing the st3 MTM tommorrow.... I hope the M23/M25 isn't TOO congested tommorrow afternoon

must excercise restraint....must exercise restraint.....

(actually, on that, will I have to uprate the clutch for the st3 extra horses? or not neccessarily? I know I did have to in my 1.8Tsport as it couldn't deal with the st2 torque - which cost an extra 1300 quid because it was the 5 speed box )

RS4/6 Calipers are now £453.68. Pads are £244.08 as of todays price upload

Nige, how did you measured it? I got those also yesterday, and the thickness is 61 mm with a new pads. (from the pad surface to the calipers top.

That it too much for my wheels, I probably have to sell them if I can't make enough space for them by removing material from here and there...

Does anyone have any idea how much could I take off from the caliper's surface without braking it?

[Nige_RS4]

Okkim, you could consider fitting a small 3mm spacer?

[okkim]

I think not, the wheel is 10" wide and ET10, it is already right on the edge.

Which disc have you got?

[okkim]

It is the B7 RS4 disc. I have been wondering, that could it be possible to change it's offset somehow. It might be possible because it is floating.

[MarkB]

The RS6 disc will move the caliper in slightly. May be worth looking at?

[okkim]

But the caliper is bolted straight to the that thing what name I don't know in english ? Does it need spacers then? I would like to keep those B7 discs because I think that they are better. Well, in next week I know what I have to do.

[MarkB]

To use the RS6 disc you need a caliper bracket to mount to the 'upright' and change the offset

The RS6+ disc's aren't bad. They aren't truly floating but they have curved vanes and are handed unlike the B7 RS4 disc

[okkim]

Now I have tested the brake and wheel clearance. It needs a 22 mm spacer, then the wheel won't touch to caliper. And then the wheel is about 25 mm outside the fender.

I could move the disk and caliper 10 mm inwards, but that is not enough. Damn.

What wheels have you got to give you such a huge problem??
