2015 Challenger R/T Plus 8 Speed
8 speed and I launch around 1500, hoping the new converter will help with this. I thought their adaptive shocks are what made a difference too, as well as springs. I am really leery of buying dedicated drag shocks since I can not use adaptive ones.I personally have not had good luck with the NT05Rs. I ran them on my Cobra and did not hook well at all. The suspension on a 1320 is completely different from an RT. Our springs are specifically set up for the drag strip and are pretty darn good at transferring weight. They are setup just like the demon springs. I know you couldn't buy the Demon springs but now you can under the 1320 part number. Since you are a manual what RPM are you trying to launch at?
