Need a little help...
For street and occasional strip, you should be fine with your factory rear springs.
DA's in the rear are nice because you have full control over the tire hit (compression setting) and how long the weight transfer stays back there (rebound setting). With 19 adjustments on each channel you can tune to your hearts content and make changes as the car gets faster and needs different damping.
