First of all, I'm NOT a car expert, so please dumb it down for me

I am doing this purely for aesthetics, I couldn't really give a bum droppings about handling yet.
What are my options?
I can't seem to find any coilovers in the UK without spending silly money, all I can find are 30 and 35mm lowering springs on ebay. Has anyone cut springs? (either aftermarket or standard springs)? Do they still fit well into the bottom/top (don't know the word sorry - but the bit that sandwiches the tops and bottoms of the springs - yes i'm a massive noob).
Also, shocks: Could anyone tell me some good cheap shocks to go for? (I'm on a student's budget) And has anyone lowered theirs on standard shocks? Does it work or is it just a no?
Thanks in advance,
Felix
