Yes I do have those wheels. But they are on an 88GT.
They are 17x7-38 5x100 with 215-45's on front
and 17x8-35 5x100 in rear with 255-45's. They are kind of tall in back but that is the size that is called for on the 3.5L engine conversion with a 4T65E. That way the speedo will be correct.
I have not noticed any problems with the suspention.
You cant see from this pic but the front and rear wheels are a little diferent, like the 88 GT wheels. The rear wheels have a 1.5 lip and the fronts are almost flush like the front 88 wheels

I like them that way, it makes it look kind of stock.
The rears are very agressive looking.
