Which rear springs?

[m52 e30]

I currently have an e30 m3, bilsteins/h&r sports but I would like the rear to drop down a bit more, any good spring suggestions aside from coilovers? I like the h&r rate but could go a bit stiffer. If anyone has anything im looking for as well PM me w/ the specs&price, I need to take care os this asap. Thanks,

some people talk about taking out the spring pads to lower the rear more. I'd look into that. Don't know if it changes safety/comfort though.
