I'm preparing to mount 335/30/18 inch tires on the 18 x 12 wheels that I want to order. I want the DEEPEST DISH possible without messing up the bearings or have that rear wheels sag over time(where the bottom diameter of the outer wheel sags out a little further than the upper part as viewed from the back of the car i.e. Ricers/Low Riders with reverse offset wheels.)
I will also order a 9 inch Ford Rear and cut it to accomodate the wheels w/ backspacing I choose. What backspacing do you guys think would look killer yet function well?? Although ideal due to wheel centerline would 6 inch backspacing give me enough dish?? How about 4 inch backspace maybe?
Attached is a link of the deep dish I would like although its a 17 x 13 wheel. Again, my rim is 18 x 12.
Will the 9" be narrower than stock? If not, you don't have too many options for BSing. Are you converting to disks? Have you added enough BS to account for the rotor? What's will your total rear end width be? How much are you mini-tubbing? What's the section width of the wheel/tire combo you're going to run?
As you can see, there are A LOT of variables involved.
