Springs = stiff as he|| Sportlines... No drag suspension.forpit2000gt said:does the car have the factory springs and shocks all around? I said before and will again, If those are are the timeslips, your engine is modded more than you know. It is possible to get to 12's without cams but requires weight savings and a very , very good driver. You would have to power shift. One of the first to ever do it was in Florida. That is about as close to sea level as you can get, in some places , below. That was with around 260 rwhp I think and weight reduction.
No weight saving, I even had a helmet and a great lunch in the car.
