Strongest/strongest/strongest/nearly the strongest but quiet on the road/ stock noise on the motorway!
I recently drove a 5 speeder ppg with helical synchro 1/2/3/4 Stock 5th and it was like a stock 5 speeder, really nice.
Straight cuts sure do whine but are robust and sound great to many!
What was the noise on the ppg you mention above 911? I know the straight cuts whine but what about the helical synchro ones? What sort of torque would this box take?
