Which lowering springs and size for e36 m3 evo cab?

[Harms]

Hi all looking to lower the car a nice height on stock shocks, and standard 17 rimms just wondering if anyone's done this and what springs did they use and what was the size of the springs?

I know changing springs and not the shocks is not best advised however it's just temporary untill I can afford some coil overs.

Anyone? Thanks in advance
