missing downforce at full braking

Now today I was on the road again with my car on the highway, am always over unique road conditions with which calm, even stable sucks up with increasing speed the Calibra on the road, no comparison to the Mercedes of my father who gets nerösser with increasing speed …..no the chassis is already class but today I came again after a long time in a situation where a vehicle from the right suddenly without blinking ,despite free Track changed to the left lane……… now what do you do there…Ancker throw of course from 200km/h … the ABS spoke immediately, regulated ….but what I noticed, 2years ago I was already in such an acute situation… The tail becomes powerfully light at such a delay but……a feeling of dancing, would almost claim despite the good aerodynamics because it is otherwise like a flounder….does there powerful drift ….. very nervous…there you think that the almost fly off, Are you also …what is your impression in such an extreme situation……or is something wrong with the brake force regulator….Well, everything went well again..even if it was very short,and the other vehicle could still pull back,and its error in the ruchteil still recognized…. But for a good blood pressure it was enough anyway….mfg
