A Dumb Question But I'm goona ask it anyway...

I am thinking about fitting a set of Eibach lowered springs to my 1992 8V GTi which is running on OEM-stock springs and Shocks...
Can I get away with just fitting new lower springs or do I have to change everything....
Do I need any special tools to do it and is this something a novice should be tackling??
Any Advice Greatly Appreciated...
