Came across this on KW's website. It allows you to raise the front end of your car up to 45mm to get up driveways, over speed bumps, etc. There are 2 kits: a universal kit to add onto your existing coilover and another kit that includes an integrated KW coilover.
Wondering if anyone has this and what your experience with it is.
