Rear Coilover spring size?

[facemelter71]

What weight spring are you guys running for your rear coilovers?

Ive got:
89 coupe
Nitrous bottle in back mounted in the center.Battery in right rear.Probly dont make a difference in spring weight but I thought I would add that.
Street strip car.

I have springs right now but I cant remember the size of them.Im just curious as to what you guys are running in the rear so at least I have an idea.
