Just one last minute thought. Do you know what tyres are going to be fitted. For ground clearance I would strongly suggest 205/65 R15. You also have the option of having a spare that is using the slimmer 4/4 wheel and tyre 165/80 R15 which has practically the same diameter as the 205/65 R15.
They are 10 mm higher than the 205/60 R15 tyres fitted to some cars. 10 mm can make a lot of difference over spped humps and such.
If you wanted to do so it may not be too late for this detail.
