The offsets on the back are for sure not correct. The rear end is narrowed to run 15x10s with zero offset (5in backspacing), so I'm sure the rear spacers will have to be significantly thicker. Also, the bolt pattern has already been reduced from 5" to 4-3/4. 120mm is 4.724", which is ridiculously close to 4.75. I wonder if they are hub-centric wheels?
