Which Lowering Springs?

[kustomss]

I plan on lowering my '85 Monte SS clone for a better look and better handling. I'll probably be using drop spindles but what lowering springs are best? I can get both front and rear Ebiach springs from Jegs for about $220 so has anyone had experience with these?
