thinking about getting the set of replicas.

I did notice that the offsets for the ones you find on ebay aren't the same as OEM ones....

ebay: 20x9.5+45 20x10.5+40
oem: 20x10+40 20x11+37

compared to my stock 19s:
ebay: front extends 9mm
oem: front extends 21mm

if I wanted a staggered setup the rears extend 36mm (holy crap)

tire weights are interesting too. RFT 19" is 9lbs heavier than a 20" non-RFT.... while a 20" wheel is about 9lbs heavier
