The 09-14 nismo wing generates something like 150 lbs of downforce, i read that in an article a while back but can't find it anymore. Versus several hundred lbs of downforce generated by a GT wing. I've known people who have had to reinforce their hatch and had to put padding over the rear tail lights because the downforce was pushing the hatch down so much that the lights were cracking and the hatch was beginning to buckle.

Like everyone else said, don't run a GT wing without a chassis mounted front splitter. You won't be doing yourself any favors.
