first day driving my dc5r !

[type_AHH]

since you put them on have you noticed it understeering of oversteering more or less since it was stock

The rear bar definitely makes the most difference.
Overall driving on the street, even on the stiffer setting (Whiteline is 2 point adjustable) the car behaves as normal as you can expect. During more spirited driving, understeer is reduced and if pushed hard enough (on the very few occasions I have), the car can oversteer but it's quite manageable.

With the front, to be honest I don't feel a noticeable difference at all.

Most other DC5R owners I know/talk to tend to just use EP3R front sway also, mainly to clear after market header.
I feel that it's adequate for a majority of people.
