The RoW M030 sits lower than the US cars do, and is sprung stiffer and more damped. I had installed this setup on my 02 S (which comes with springs, dampers, and sways) and it was an extremely well balanced car with it installed.
If you want to raise the ride height, just swap out the springs. However, depending upon your mileage, it may make sense to replace the dampers as well.
