5 lug swap is more than you think. ask casey. he was going to do it and buy my old rims but after he got a price on everything he couldnt do it. i think he said it would cost nearly 450 to 500 for the 5 lug swap.
as for the paint, do not do silver with silver rims. then u will have to much going on. the G2 caliper paint is a bright red. looks good after you put a clear cote on it. will stand out against your paint even tho its hidden.
so i would look into maybe black. but after you do the clear is shines blk and looks nice. im doing my blk here soon. and the research that i did.....get the G2 caliper paint.....well if you can get any pics of what their gold looks like then maybe try that. but IMO i would do blk.
