adjustable and comfort won't go together unless you're willing to pay (say, 5 digits for RCS 2/3 ways?

)
adjustable is as the name implies, adjustable suspensions, where it's typically coil overs - very short spring coils. considering the coil lengths, the amount of force it can absorb/disperse is very limited, hence almost every adjustable/coil-over out there in the market will have comfort/nvh severely compromised.
sports in general are typically lowered sports spring, and/or stiffer absorbers (some even have shorter stroke absorbers such as IMP propex to further lower ride height)
basically, they offer minor performance upgrade, while generally/mainly lowering ride height.
comfort is going to be compromised as you may experience bottoming out especially if tend to drive/corner very fast.
whatever you change, of course the ride won't be the same, else why you change it if it's the same, right?
at the end of the day, it really depends on what you want, what you're willing to pay, and understand what you're getting into.
tldr: why didn't join us on RCS? please refer previous posts regarding RCS.
from what i understand from above comfort and performance dont comes together even can the price tag going to be high
rcs group buy penang kia hardly can afford to travel to KL just for tuning unless already know the setting he wants already fix
