but as you had pointed it out, it is an over kill for my needs. I never tracked the z before, and only use it as a daily driver. But iam in a process of swapping a brand new engine into the zx, so i really like the stopping power and it might save me in one of the trafic jams. Sometimes driving on the freeway in trafic some car in front of me stops so rapidly i hit it all the way, and several times i can feel my car just stopping so hard that the car in the back of me is swerling to the left trying not to rear end me, its funny.
