how to lower a megane II more

[Daz2014]

hi I have a megane II witch I have lowerd 30mm on apex springs its on steel wheels at the mo I have a set of 17inch alloys to go on it .I have had two 205/55 r17 tyres fitted and they look good gets rid of the huge arch gap witch I want but im un shore about the 55 side wall would rather have a 45 side wall but a 45 side wall is actuly a smaller diameter than the wats on it at the mo and would make my arch gap bigger witch I don't want .the rear spring can be cut with a grinder but the front cant .so heres my question finally how can I lower the front more without new spring or coil overs witch I cant afford now...Here's a pic with the alloys with the 205/55r17 tyres ..thanks for reading....Im unable to upload picks as the Img button only does this If some one can help me upload I will
