I've got the same car and have moved from Eibach springs with Boge Turbo shox to Wietec set damper shox and 30mm springs. These are fantastic as I do track/driver days

Wietec do a front coilover with 4 point adjustable rear for about £300-350 and are fantasic as you can go from 10mm to 50mm front and rear.
Give Storm Developements a call
http://stormdevelopments.co.uk/ and speak to Andy or Miles. They can do the fitting as well for very reasonable rates.
All really depends on what you want it for. If you want to go quite low for cosmetics then go for the coil/set ones I mentioned above, if you want performance mainly then the ones I used are great, although the fronts are a little higher than I'd like if going for looks...but as proven on my trackday last week, the performance of mine where amazing considering I was up against Evos, Scoobs and Celicas

I run 17" OZ polaris with 205/40/17s and with the Eibachs they did catch slightly without damaging the car....but as said I do track/driver days and the treatment is more than you'd get with even hard driving on the road...but the new ones do not catch at all as have the rears set on level2...they go to 4
