Front rim offset

Taking my stock wheel apart to install an Xcell , in 19 WM2, I measured arounf .515 offset from the hub/disc place to the outside of the rim. does that look ok? will I need more with the CNW Brembo?
Thanks

From the disc flange on the hub, to the center of the rim is 1 7/8" If you use this measurement it dose'nt matter how wide the rim is.
