Eibach drag launch kit with airbag, lakewood 50/50 shocks in the rear and 90/10 stuts in the front will give you a nice drag friendly susp.. If you want a little better street manner then change the lakewood 90/10 strut to a lakewood 70/30 strut.
That drag launch kit by Eibach works well but the car sits up too high for me. Laurel Mountain Mustang makes a drag launch kit with airbag too about $50 bones cheaper though.
Lakewood shocks/struts ftw! I love mine as for springs I went with ford racing C springs kinda wish I had the eibach pro kit but I'm still satisfied with what I got. Ride height maybe dropped half inch front and rear if that.
