Questions for other 2.5i manual owners

Well obviously you can learn the characteristics of the clutch with a cdv fitted just like you would any clutch but in my experience the cdv makes you drive like a granny hardly what you want from the ultimate driving machine is it.

Methinks you need to practice more granny.
Or should have been born early enough to learn on 70s and 80s cars.

I drive a 50 year old tractor at work does that count lol

Well I doubt it has a CDV!

So I'm not sure why you'd want one?

I removed my cdv and never looked back, yeah I learnt to drive with it smoothly but it took the fun out of driving a sportscar

I wonder if this is connected to the recent discussion about clutch travel? The cdv works as a one way restrictor, slowing the return of fluid and therefore making the clutch take slightly longer to re-engage.
As this is a linear function it makes sense that if you only depress the clutch far enough to disengage, rather than flat to the floor, then the time taken to re-engage will be less.
Could explain why not everyone sees a need to remove it?

Seems logical to me, have read plenty of stories where people don't notice a difference with it gone, but I noticed a vast improvement, it's my understanding that it doesn't matter how quick you bring the clutch up the valve controls when the clutch engages not your foot I always felt I had to give the car a ton of revs to allow for this delay

The E85/86 Z4 sets off best in 2 ways.
Nail it, CDV is an advantage.
Baby it CDV is an advantage
Anything in between I seem to struggle with (except my 2.5i E85 that was perfect with 130,000 miles, an utter pleasure to drive)

Sorry but you're just wrong IMHO.

Why nail it and rely on the CDV when you could get the clutch fully engaged sooner then just floor it?

Let me put it this way. I have had 2 Z4 cars and I prefer them with the CDV fitted.
I feel with the 3.0si in particular you could do some serious damage without it.
(Don’t tell me you can drive better than I can, you don’t know me, I don’t know you).
Your car may also get driven by garage mechanics etc (I try to avoid this at all costs)
The difference between fitted and not fitted is barely noticeable IMO.
