alot of import cars ebrakes are alot tighter than domestics. my eclipse could lock them up easily by ripping up the ebrake, i used to whip 180's all the time with the ebrake-skid method(since it was fwd) same with my buddies integra, now his srt4 and even my moms neon locks the rears with the ebrake.
it might have something to do with the weight of the vehicle and the tension of the ebrake cable and even the ability of the rear brakes.
BTW. when trying this maneuver, do NOT let the ebrake click. hold down the button to let yourself have full control over the ebrake. the button is only to lock it in place after the car has stopped.
