Cheers, 
            I think i'll invest in a set of 25mm spacers and stick them on the back and the current 20mm will then go on the front, should look   
tempted to lower the car has well by 1" at least any suggestion would be appreciated  
  
Sunny, Eibach springs will give you a 27-30mm drop, close to about an 1inch drop...    They'll also work really well with your spacers, let me know if you want a set...
