Talked with QA1, need some input

[Aaron'S'tang]

I called QA1 to see what they have to offer for my car. They have a kit with k-member, coil-overs, and rear shocks for $1500. They do not offer springs. I currently have an Eibach 2 in drop spring set up. I need softer springs. What do you guys have. Who makes rear springs for Drag racing? I really want to get the best stuff so I don't have to do this twice. Is anyone using stock springs? Thanks for the input.
