thanks jyosh - I like the X6 wheels too, not sure if someone had put it on their 4.8is and tested them but they say it should work.
Hit Redline - I spoke with the Insurance Agent again and he told me to leave it the way it is till he shows up for estimate.
I did some research on tirerack however i dont like any of the rims they have, however that would be one option to go for if things dont work out, in the meantime i will push to get OEM wheels and tires from the insurance company.
