Going from a restalled D5 (orange stripe, ~ 3000) to a 3400 stall Vig single disc was by far my greatest move. My 60ft went from the 2.2 to 1.7 range and 1/4 times went from 13.6 to 12.0's. Well worth the added expense!
Im not worrying about 6OfT times as much as how fun the car will be to drive on the street.Uncontrollable wheel spin is not what Im looking for.
