Yes, where indeed to move the rad. I have however fitted a duct to try to make most of the air go through the rad, rather than round it. Its pretty miserable here, so a partial grille block should be liveable with.
Got a mobile alignment company out, and for 60 quid ($97) he found a misalignment of 4 and 5 degrees, toe out. Wow. Set back to zero now. That should help.
6" front air dam in place, with about 5" showing under the front bumper.
