Below is the specs for G70. I got the FC04
rims with +40 offset 18x8 5x114.3 72.6Bore. I tried to fit the
rims and they fit perfect, the only thing I am worried about is that the front
rims inner lips are close to the shocks and I am afraid that they might hit them. I will find out more when I go to have them mounted. Although, Fast Wheels Canada states that you can go upto +42 Offset all four wheels since they have a contract with Genesis Canada to make
rims that fit the car.
I would suggest to stick with +35 offset 18x8 5x114.3 67.1(Lowest Bore Size G70 can take) and you should be fine. If you pick a
rim that has 67.1 Bore it will be a direct fit without hub rings. Otherwise I recommend getting the hub rings it will help with vibrations.
