Out of the box, the KWs are definitely faster because the entire kit is built as an integrated system, meaning the dampers are built for the specific springs, ride height, tire use, etc. For the Moton set up, I spent a lot of time and received help from two racing drivers to tune the set up properly.
But after the Moton is tuned in, the systems are equally good. KW has a slight advantage due to stiffer springs.
