For anyone who knows about this, i was wondering what people felt about yanks very high str, which says it will loose top end efficency. And if anyone has a vig 3600, what there str is.

 

I think you can get a number of different manufacturers stall w/ different STRs someone else will need to chime in though. I'm lookin @ a Vig or Yank SS3600

 

me too i think im just gunna do the yank 3600, the 4000 is alot, allthough they have the pt 4000 witch is a lower str (2.2 as compared to 2.5 and 2.6) so it wont shock the tires as much. But then, i thought about how loose a 4000 is already, and then with a 2.2 itll just be that much looser.

 

A PT4000 and 3.73's is not really that loose and is very fun to drive. to address your original question, Yanks at their highest STR are still more efficient than Vig's when comparing the same stall speed.
