Fancy coming and doing it to my car?
Once I've done it to my Z4MC, I'd be happy to get the appropriate brackets produced if there was sufficient demand to make it worthwhile.
I'm off to pick my Z4MC up now! WoooooooHooooooo!
Cool - and get some pics up!! Where are you based by the way?

This is how I've done mine on my Z3MC and the parts have been on for several years now and had no problem. The inlet is attached to the front ARB. The air comes from underneath directly off the engine undertray. I found that the key to getting them right was having the ducting just long enough on full lock so as not to be stretched and also routing them so that the ducting doesn't have to make any 90 degree turns. I've used a digital pyrometer to test their effectiveness using another Z3MC without ducts as a control and they really work! I'm sure I'll find a way of doing something very similar on my Z4MC.
Clever wrench monkey!
NO mods needed for road use tbh. As Beedub says OEM is OK for track use but just a for a FEW laps and proper cool down lap or 2 (no handbrake on parking afterwards either). Saying that I fried mine on my 3rd trackday to tbh I was being a bit "keen" and utterly talenless
Braided hose like Goodridge, track pads like Pagid RS29 (noisy messy bastasr*s) and new disks do a great job with DOT 5.1 fluid).
They are actually quite close in weight. The illusion that the gap is much bigger is due to the fact that the E46 M3 CSL (without air conditioning) kerb weight was originally quoted as 1385kg. The issue is that the EU kerb weight is quoted with an additional 75kg allowance for driver and luggage. The EU weight for the M3 CSL is 1460kg, EU weight for the Z4MR is 1485kg and 1495kg for the Z4MC. If you add air conditioning to the CSL, it will likely be heavier than both the Z4Ms.ga41 said:
i felt the stock brakes were brilliant and when i had the rotors in my hand i could definitely see they were a quality piece... no doubt about that at all.....
it was only really the power increase that really tested them, one sprint session really killed them.....
I havent as yet felt fade with the ap setup BUT i have had them smoking and the rotors turned bright blue..... still no fade however.
ive driven and owned alot of fast motors but the Ap bbk setup currently on my car is nothing short of breath-taking...

I'm not a particularly heavy braker and haven't goosed mine at the 'Ring, Oulton Park or Cadwell Park.
Although I did put non-OEM pads on as soon as I got the car - and they lasted over 30,000 miles.
If money were no object then I'd have an Alcon set (and I keep asking my mate to let me use his from his CSL as he hardly drives it)

I found the OEM set up very good but I finished of a set of pads in one track day (they were far from new before hand). I then changed to EBC yellow stuff and uprated fluid with a significant improvement on the track, and with excellent pad durability. The only down side I've noticed is that the pads work less well than OEM when they're cold.
I did manage to get smoke pouring out through all four wheels after a fairly short track blast when I neglected to switch off the DSC but after a gentle drive to cool the pads and discs, they worked perfectly well for the rest of the day (DSC switched off of course 
).

What you didn't notice the blinking yellow light?
Unlike Mmm5 I'm a rubbish newbie track driver and I did in all honesty cook mine on my third trackday by just getting carried away and not following procedures to keep them healthy. They are great on the road though. DOT5 and track pads can be tiresome in traffic.
