I got the rear anti swaybar, together with Whiteline endlinks, installed today. It's a 2 way adjustable ST (exactly the same as KW, just grey instead of yellow). It's set at it's soft setting.
The install could be better as the endlinks shouldn't have been mounted centered in the lower control arm (it's adjustable). Next up is changing the control arm to camber adjustable SPC, however I need to take the car to a mandatory inspection and I'm not sure they will approve of the SPC arms. Hence they will be installed afterward and I'll correct the endlink position at the same time.
Since it held up to being babied yesterday, I took the car for a thrashing on a small back road.

They swaybar install didn't make any noises despite the endlinks sitting at an angle. Despite my still lacking alignment, the car handles surprisingly well, definitely flatter in the curves and it felt there was reserves to levels where I didn't want to go.
I am satisfied so far... More to come.
