i need somones help....lowering my civic soon!

i had a vauxhall nova, and they are absolutley piss easy to lower. im guessing my civic will be harder.

im putting on -50mm springs only (dont worry about damaging shocks..all in good time).

so basically is there a guide how to lower it? can someone tell me what to do and look for?

i drive a 91-95 esi vtec.
