well with the softer springs in back it will let more weight transfer to the rear which will probably help you get better traction
I'm with JL on this one. I am cutting 1.73 60 foots on lowing springs with 260 horsepower and not alot of gear... sports would be better but not in the budget currently. Wheel hop will kill you with soft springs. Especially if you have some power.
One thing i have noticed is that most of the better 60 footing t birds have got airbags in their springs or a minimum of their right spring.
