Re: KW V2 coilover for F10
Correct for most part except the very expensive option that includes active stabilisation and softening of the EDC depending on road conditions and driver input is called Adaptive Drive as wt_know mentioned.
If have this system only then you will get COMFORT + in your DDC menu, otherwise most will get only COMFORT.
Adaptive is the system that comprise the EDC (adjustable damper) and Dynamic Drive (arb thing)
I am very interested in the Dynamic Drive part whereby it is said to be an ARB cut in half with a motor in between that twist the ARB in the oppostie direction that your car will twist it during a corner - counter the cornering force.

Re: KW V2 coilover for F10
Had a chance to take a look today and I saw that yes, mine has the pre-stressed springs installed as well. Just FYI
wt_know;1011567 said:today sent in the car to install the pre-stressed spring
after installed the pre-stressed spring i find the ride is actually harsher
look at the pre-stressed spring being compressed almost back-to-back and yet the car height is still below my expectation
at the end ask the workshop to remove the pre-stressed spring and redo to original setting
collect my car at 8pm. the guys working OT on my car to get it done
i thank the workshop (it's FOC btw) and probably going for another mod liao ... the dark force is sibei strong

Re: KW V2 coilover for F10
Won't be dangling.
With or without pre stress spring the main spring is under the same load.
The car will be even lower (assume you dun adjust the seat ring upward)
The pre stress spring is meant to be completely / almost completely compressed under normal condition.
Only when your car is on the rebound up after a hump or ridge then this spring comes into action.
It stretches and prevent the main spring from coming off its seat

Re: KW V2 coilover for F10
pre-stress spring and some called helper spring
1. to prevent the main spring from coming off its seat (as explained by jason) because for slamdown ride the spring is wide open and may not tightly secured by the purple ring
2. to prevent bottom out for slamdown ride especially go through pot holes

Re: KW V2 coilover for F10
aiya ... why so itchy want to remove it ... if already installed then continue la unless there is an issue
to me ... the pre stress spring does not matter much because my ride is not slamdown
if slamdown, pre stress or helper spring is critical
my ride is high (2.5 fingers front, 2.25 fingers rear) the pre stress spring make it more complicated nia
the main spring is already quite compressed and secured liao to push up and support the car
hence, the purpose and benefit of pre stress spring is less relevant in my case
look at the 1st purple ring nut position ... it's hardly 1/2 way down the threads ...

Mine is not slam down also. 2 fingers front and back. So the thing also useless like deadweight.
