Apex claims that the Arc 8 18x10 weighs around 19 lbs, and it's 1/2 inch wider. I prefer the look of the OEM wheel but if I can save around 8 lbs of unsprung weight per corner it's a no brainer. I'll go the with Apex.
On the other hand, my OEM rear with worn out PS2 weighed within 1-2 lbs of the 18" Apex with 285 R-S3's, at least according to my bathroom scale.

I'm curious enough about the discrepancy to try to weigh them in a more rigorous manner come spring.
