Good car and a good price Danny

Welcome to the forum.
It is a steep learning curve if you are going down the modding route with your car as there's tons of info out there on the web.
Like T_T says they are 5 x 112 wheel fitment and just to add the stock offset is 51.
Are you simply wanting to lower the car for looks or planning to adjust them for trackwork?
You may consider springs if you just want a better stance

I'm running on Eibach Pro Street S coilovers at the minute, but considering an upgrade to the new Bilstein B16 PSS10's
Maybe you need to have a look around the forum at some of the historical posts on coilovers, set yourself a budget and start a specific thread off for coilovers as it is an awfully big topic
