The Sierra has had problems to pass the german "Gütesiegel" certification in terms of sufficient pitchup.(legal) topspeed was set to 70km/h. To me, it seemed the production Sierras had longer lufflines and lowered sticks than what had been certified... I once tested a Sierra of my friend,who claimed it to go faster than 100 km/h. I stopped the test at 110... In the complete speed range, there was basically no bar-pressure ... Many tumblings have been reported - no wonder.
