Enkei RPF1's come in "Vanquish White".
I have a set of 17x9 and they're super lightweight (15.xxlbs). Depending on the specs, they may require hubcentric rings and PCD-variation lug bolts.

Did you have a budget? All of Braid's wheels come in white as standard and are indestructible. You'll pay the price though, an 18x8 in their Fullrace is $350 and that's about the cheapest. Custom offset is nice though.
You could also get anything from Forgestar in white. A set of their F14 run about $1400-1500.
