As for th cdv..its the CLUTCH DELAY VALVE.
You can get a modified one of these,or modify it yourself. available from the likes of zeckhausen,which improves/gets rid of the jerky change you can get between 1st/2nd gears.
BMW over-engineered the car with this being fitted,as it cures a problem that doesnt exist/ie makes bad drivers able to change gear,haha.
It causes jerkiness in lower gearchanges,almost making the car die on you inbetween gears at times...SO A MODIFIED CDV IS A GOOD MOD(Basically a blanked off cdv)and easy to install

I've read on a number of boards that the CDV can simply be removed at the hoses connected directly, without a modified valve. What's the benefit to modding the valve instead of removing it?

A modified valve is only for if you still have a bmw warenty,

ie. still new So personally i would bother putting a modified one back in just connect the hoses back up

^ X2. Done the CDV removal to two different Z's meanwhile and driven over 70,000 km since (the two of them combined): works perfectly fine.

Love the steering wheel and the seats!!

Have the say the standard seats are very disappointing when you turn into a corner. A slightly younger Hyundai has better lateral support...

This is a complicated area and a minefield of hybrid bio-mechanical vs pure physics formulae exists to prove that this is in fact wholly dependent on the the size and shape of your arse.

what do you mean by foam removed from sound generator? what does that do?

Lets more noise from the engine into the cabin,

the foam is just a noise baffle, and with them removed you get a noticbly louder engine sound inside

ah right, where is this bit? i find with my 3.0l i get an annoying sound at certain revs. it really resonates in your ear and can be a little unpleasant. not sure i want more noise but maybe the lack of foam will change it a bit. cheers

If you suddenly get an odd fairly high pitched noise across a specific rev range it sounds like someone has previously removed some foam from your sound generator. I tried this mod after reading about it on here but immediately put the foam back as I didn't like the noise it made (a bit weird and not becoming 3 litres worth of 6 cylinder power imho).

From the engine bay you can pull out the end of the hose nearest the cabin quite easily without undoing anything and look/feel to see if the foam insert is present.

The Zed is too quiet in the engine/air intake/exhaust depts but for me the sound gen mod just wasn't the answer. Now a quad exhaust, maybe that would.....stop it! Stop it! You're making me do it again!

Today i fitted braided Stainless steel brake hose's, DOT 5.1 Fluid, removed the clutch delay valve and painted the calipers:

Front and back brake hose's:

The set of hose's i bought: http://www.camskill.co.uk/m50b0s4061p84062/_HEL_BRAIDED_BRAKE_LINE_HOSE_KITS_-_HEL_Brake_Line_Kit_-_BMW_Z4_3_0_E85_2003_on_ Im a bit annoyed with really because i assumed this would be all i would need to do the job, after jacking the car up and a bit of messing arround I find out the rear has two sets of hoses for each side. So to do the all the hoses front and back you need 6 hoses where as the kit only has 4

I have sent them an email i will see what happens

Nice touches on the car love the lamin-x on the lights. Who did your steering wheel?

Excuse my ignorance too but what's the dice mod? I keep seeing it, seemingly relating to audio/ iPod but can't work out what it stands for

Thanks very much,

Yea im impressed with the lamin-x I tried doing it with window tinting film first but couldnt do it as it kept creasing and bubling. The lamin-x is cut to shape so it fits near perfect, i only have one small crease that you cant really notice

I got my steering from this guy: http://royalsteeringwheels.com/ highly recomended

The DIce is just a manufacture for an Ipod adapter: http://diceelectronics.com/support/files/bmw_dice_gs.pdf

it basically plugs into the cd changer wireing and allows you to control and listen to your ipod throught the head unit, you get all the track names etc. on the diplay
