BBK concern

You Will probably lose your handbreak then as you go full BBK, guidok from the dutch forum, has fitted the "performance" brakes from bmw in the rear but he had to do custos work on it. His discription should also be over At zpost i think


Edit this one http://www.zpost.com/forums/showthread.php?t=751080
 
AP, Alcon keep handbrake along with D2.

Mate just fitted some Alcons all round and they are lovely.

I might go D2
 
you should still keep your handbrake.

IIRC the handbrake issue was only if the rears had drums which our cars don't.

AP bbk front and rear, everything operational as per a normal car, no mods needed....
According to the AP site they only deliver sets for z4m and not for z4 (not interchangeable).
Maybe they do custom if you pay them enough :lol:

Cheapest and easiest will be something like D2/ksport/insert random taiwanese brand....

My rear kit is pretty experimental and not suited for someone who doesn't have a lathe or a TIG welder or so.
Then again the complete rear section (including discs, bmw/brembo performance calipers, pads, various parts to tinker with... etc etc) probably cost me less than 300gbp :roll:
It was so cheap because ecs had this ridiculous sale on the rear calipers ($198/set, instead of $563/set), so I obviously included them because I already was ordering so shipping was also almost nil. And I wanted something to match the fronts of course. This bbk setup has a nice 'OEM' feel to it because the calipers are BMW parts (just not from a z4). And it is something most others don't have.
I'll probably make some improvements sooner or later.... to keep myself busy :wink:

Fronts were also cheap (back then). 800gbp or so incl shipping (from ecs tuning, now they're already 1000gbp ex shipping (ex vat)).
 
Can't you fit a slightly smaller disk at the rear?

356 is pretty big. The rear can't brake as hard as the front (due to shifting of the dynamic axle load to the front).
So it is pretty customary to run 1 size smaller in the rear. That way you save dynamic weight on your suspension which improves handling. (so front 356mm, rear 330mm, or front 330mm rear 320mm etc)

Or are you going to run 380mm up front? (that is really big)
