I've just done 6 laps at the Ring this morning and the KW v1 coilovers are nice but a bit too soft

The car is scraping everywhere haha, had to remove the wheel arches as one side completely melted and it's scraping like crazy especially on the Karusell!
I think with stiffer springs the rear would be less unstable. Does anyone know the spring ratings of the KW V1?
