Can we fit 11" wide rear wheels on our cars?

Hey guys,
I may have screwed up. I bid on a set of wheels I liked on E-Bay. However, I am not sure if they will fit my car. I bid really low, so I figured I wouldnt even win the bid. HOWEVER, I checked my E-Mail this morning... And WOW I WON!!!

The wheels are a replica set of 17" Chrome ZR1's.

Fronts:
17" x 9.5"
+56mm offset
7.4" Backspacing


Rears:
17" x 11"
+50mm offset
7.93" Backspacing

I have a 4th Gen rear axle that I am planning on installing soon. So I am hoping that that will take care of the rear wheels. I will probably have to get a set of spacers for the fronts. Any ideas how thick I should go?

Thanks for the help.

you will need 2" wheel adapters to fit the wheels all the way around to make up for the offset, our cars require 0mm offset +/- a few. with the 4th gen rear, im not sure, you would have to do a test fit to make sure. 275/40/17 are needed, but with the 11" rear wheels the tires will look weird on the rim, so if you can make them fit, go with 315/35/17

Its awesome till you have to buy tires. The cheapest decent ones I can find are $250 a pop!!!!! The way that I go through tires, I would have to get a 2nd job to afford them!!! I think I am going to go with 9.5" rear wheels. Mabey I will get the 11 inchers and just use them when I go to shows?
