Everytime I went to the track with my Firebird, the posi was broke and it was a one wheel peel. My 60s were always in the 2.2-2.3 no matter what. Even with my DRs, the best I mustered was a 2.1x. The motor is in pretty good shape so I really don't think that has to do with it. I may be wrong. But will my launches improve with 2 wheels turning vs. one?

 

should almost feel like two tires hooking up,

the question is did it spin the one dr?

 

So yes it will improve my 60fts?

Did the one DR spin at the track? No. I had those bastards at like 15psi. Which I heard is to low. Should've had them around 24psi or so.

 

if it wasn't spinning the one, its definitely not gonna spin now

so no might not make much diffrence

 

With DRs on the street the one tires still spins quite a bit. I guess, the most important thing is instead of an embarassing single long burn out streak, Ill 2 shorter ones.
