I just ordered my lowering kit for my 2013 GT. Got the eibach sport line sport kit 1.3 inch front and 2inch rear drop. Still running stock rims with 245/45 19's but Wana go wider anyone dropped there car on stock rims and gone wider Wana know what size I can go.
On my 2010 I had Ford racing K-Springs, 1.5 " drop all around. I had 255/40s-19s up front and 285/35-19s in the rear on staggered AMR rims (19x8.5 and 19x10) with no rubbing or clearance issues whatsoever.
