Has anyone had or heard any negative experiences with Hotchkis (#19391) springs on a '11-'12 GT?
They look like a great choice because they provide a nice drop (1.1"/1.6") with comfy spring rates (180 lbs / 125-180 lbs).
By comparison, Pro-Kits drop 1.0"/1.5" and Ultralites drop 1.2"/1.4".
I'd be running these with Koni sport dampers. Daily driver with autocross potential.
Here's a pic I found showing what the drop would look like:
