My V2 took about 3 months to completely settle.
You can adjust the height with any KW coilovers.
"Depending on vehicle model this varies between 30 to 70mm or 50 to 90mm. Even after years you can adjust the height quickly and easily due to the dirt resistant trapezoid thread and composite collar"
KW is having a March Sale for BMW cars. I can offer you some good price to you!
