Front drag springs

[85LXCoupe]

What rate of spring would you run for a street/strip car? I want the emphasis to be on the launch but I still want it to be safe for street driving.

I was thinking of the 175 but that might be too light. 200? 250?

With rates like that, you must be running Coil-Overs.

I run the Granatelli Drag Coil Overs and they came with 12" 175 springs, or so I have heard. Good spring but I want somthing different. I am planning on 14" 125lbs/in.
