I got new spring and shocks for my E30:buttrock
How hard is it to put springs on? Is thier anything i should know before i try and change this stuff?

you need a spring compressor to remove and install the springs on the front. You will need the upper strut bearing and spring pads from the old setup, so you have to disassemble them. good luck

Spring compressor is a must, You may want to changed the mounts while you are at it.
