Changing the absorber mounting didn't eliminate the kok kok sound when going over rough roads, but the steering wheel no longer vibrates when the sound appears. The installation of the new servo somehow reduced the kok kok sound by quite a bit.
For those who are using the B-Line/M-Line Personas with front discs and rear drums, if you want to get a rough idea of how the Evo 6 servo feels like, pull on the hand brake hard while you're driving, and while you're doing that, press on the brake pedal. The pedal should feel much stiffer than usual and "max out" just after a short travel. I normally engage my hand brake when I first start driving the car for the day to warm them up quickly to stop them from making noise, and this is also how I found that the pedal is much stiffer than usual when I press on the brake pedal. This is quite similar to how little you have to press the brake pedal to engage the pads fully with the Evo 6 servo.

Mine before change the servo, feel nothing even hard braking ( adjustable hard enuf =) )
after change servo now have the feel throw forward
Change the disc rotor with slotted and hole even better.
When brake servo upgraded, the braking power increase, the disc will hotter than usual ( depends the way u press yr brake la)
Note: My car I drive up to genting quite frequent , brake power sucks, making the downhill harder @@ Auto car
Brake power sucks, before or after servo change?
