thanks for the comments everyone
@ Kris, the last render i had to set it up using vray proxis, becuase my computer crashed evertime i tried rendering it. so the the wire frame for that shot will not really show a proper wireframe, but in have got a couple of wire shots form earlier
as for the poly count, it doesnt really need to be that high but with those rims, i have a mesh smoother modifer on them set to about 3 or 4, that kicks the poly count up a lot
thanks Tom
