New Discs: Look at these babies!

[groucho]

They do look good.

[mat205125]

Aren't they just the same as the ones that have been replaced?

[bennyboysvuk]

Very nice indeed.

Similar to a shot I took of mine a few weeks back after fitting some new disks and pads:

[Jazzer]

Those alloys are in a bit of a state......woman driver involved?

[mmm-five]

Yes they are 'babies'

You need a set of these...

Only in size. I can assure you they didn't look anything like these.

There are different from the OEM discs?

[mat205125]

Since we are posting pictures of brakes. Here are some ones I took back in February

Out with the old...


... and in with the new


little and large


a close fit


who says you need CSL rims to fit AP 6 Pots and 357mm discs?

[Windymiller]

I thought AP intentionally designed their kit to fit under the 18" OEMs?

They were fitted by BMW.

Under 18" wheels, yes, however not necessarily the OEM rims. In order to have enough clearance, the car now wears 12mm spacers on the front. This has actually improved the handling too IMO

[Paul_M3]

Mat,

Have you got the wider AP caliper then?

I was under the impression the 5555 caliper needed spacers, but the 5575 caliper was designed to fit with OEM 18's?

I hope so, as I've just bought a set of OEM 18's to use as track wheels. I didn't expect to have to mess around with spacers.

[mat205125]

Mine are 5575 calipers and they won't fit behind standard wheels without spacers as the caliper face touches the inside of the spokes

[Paul_M3]

That's surprising and disappointing mate.

Every website certainly seems to imply the 5575 caliper fits under 18" and 19" OEM wheels.

yep they should do UNLESS your tyre fitter has put the weights in the wrong place

I was a little confused when I read the AP site, and luckily I decided a trial fit was in order before I started breaking fluid seals and what not.

Mine are definitely the 5575 kit, and if you have a look at this drawing from the AP site, the key dimension to look at is the 20mm dimension from the rear of the disc bell (hub face) to the front of the new rotor.

http://www.apracing.com/drawings/p16136.pdf

Now compare to the 5555 kit which is only offset by 16mm back from the hub face to the braking surface. Open two windows side by side (or print scale 1:1 and overlay), and you can see that it is the 5575 that gives the best clearance behind the spokes as measured from the hub face.

http://www.apracing.com/drawings/p16116.pdf

It is a bit naughty of the AP datasheet to list the brakes as fitting behind the OEM wheels, without mentioning that they need spacers.

Do you run yours with 19" CSL rims normally, or the shiny shiny 19" rims? I've heard that the latter need spacers too.

I went for 12mm each side as I wanted to provide ample clearance, and realistically you're not doing to get away with much below 10mm. Using high quality hubcentric items, this is not a problem at all, and mine carry TUV approval (Eibach). As also mentioned, the handling is improved too IMO.

Maybe not the "wrong" place for a standard setup, however certainly not right behind the spokes on the flat inside circumference. Clearance really is that tight.

If you are looking for a decent brake setup, floating rotors and rebuilt calipers on an E34 M5. Just outstanding!!!!

I run the CSL's normally, so haven't had any issues so far. I don't intend to ever put the bling bling 19's back on until I sell the car really.

I have the 18" wheel available now, so I'll have to check tonight and see what spacers I need. (Although 12mm sounds like the obvious choice)
