Just in case anyone else is trying to fit bigger/wider tires in the back, this is about as big as you can go. I have signature 19x12 on the rear and was running 325 tires, but had more space. So now jumped up to 355 rears and they are as big as you can fit on this platform (27"x14").
On the front I have 19x10.5, but could easily fit 19x11 or less backspace, there is more room on the outside before we are flush.
Also of now (200+ miles driving) no issues with the speed sensors with the circumference differnce f/r using a 285/35/19 front.

Ok, we are going to need a LOT more pictures of this fitment! Thank you for doing this. The 19x11 front is what intrigues me because I have long wondered about a 305/30/19 up front.
