Hi juki48,
Dual 19mm bars on your ’74 will make your car feel very quick and responsive for street use. The front bar keeps the body roll down and keeps both front tires planted. The rear bar decreases the understeer and is the big contributor to the quick-response feel. The rear bar really enhances “turn-in” as in where you are steering into a turn and the car responds almost instantly.
But, for very high speed use, where you want understeer, a front bar alone is just right. High speed here means 100 mph sweepers where you want no sudden moves off course.
