I have Competition Engineering 3 way adjustable drag shocks on the rear now set to 50/50. I have done nothing with the front suspension at all, and I would imagine my starting point would be a pair of 18 way double adjustable Viking shock absorbers that would also allow for full range of extension and compression/rebound control.
What other front suspension mods are you using?
My point is that unless we impart a lot more power via nitrous oxide at the launch, which we don't have and haven't planned on, we are really close to the goal of optimum launch + 60ft. rear tire traction so I don't think we have a lot that is needed to do with the front end.
On the other hand, as we get more traction at the launch +60ft, I'm sure that we could get more aggressive with RPMs and cut down the 60 ft and 1320 times, so I am interested in your input.

What times are you running in the 1/4? Ideally you want 4-5" of free travel in the front, the double adjustable Vikings might be overkill depending on your times.
