need help on lowering my car

[a1an_49]

i apologise if i have placed this in the wrong place,

but i need someones help on how i can lower my car,
i havent got a clue what springs to buy, where to buy them from, how much they should cost me and how to fit them...all i know is that it needs to be done, because i dont like the look off my car sitting on 15 inch alloys...
so please help if you could
thanks

Get your self a set of billi coil overs, not sure the price prob wouldnt be far off if i said between £500-£700 no point doing anything else.
Get you self on google and have a look
