I have the Tein REs, and with the dampeners adjusted down to setting 4-5 fronts and 2-3 rears, it handles very precisely and predictably, and is pretty easy to live with overall. Its stiff, for sure, but not harsh. At higher levels, the dampeners completely transform the car with racecar-like stiffness. I tried higher levels on the street, and it was miserable.
