It depends on the tire sizes, suspension modifications, and how low you want to go.
I can't remember the size of the Rs, are they 9s, 9.5s, or 10s?
In general, you can go with 6.35 backspacing in the rear but you'll have to do some hammer work to the inner wheelhouse - especially if you're going with a 295 or larger tire.
In the front you're safe with a maximum of 4.75 backspacing.
Be aware that there's conflicting information on the fronts: 18s may clear the UCA and allow more backspacing than 4.75. Also, going larger than 8s in the front may cause problems if you're limited to 4.75.
