Hey Zbobo if you are doing the yz flares like I keep hoping to do I would seroiusly think about converting to a five lug setup or being prepared to fork out cash for custom 4 lug rims. The yz Flares can handle a 12 inch wide possibly 13 (still looking into that myself) wheel. Start considering how much those kinda wheels are going to cost you. Unless you want drag type rims in a 15 inch size you are going to have problems filling those flares. The new mustang five lug rims seem to be a favorite. IF your pockets are deep enough some companies such as volk hre and some others are making nice rims for wide body 300zx's and supra's however these are going to require a spacer at least on the rear. I would start thinking about costs involved in the different options. 5 lug swap vs flared vs custom rims vs adapters vs little selection. Id have my rims picked out if I had 2300 dollars to spend on them oh well
