Offset and Wheel sizing GODS!!!

[driftking777]

Aight so heres the story...im looking at getting some Advan SA3R ver II's 18x9 (or 9.5) and 18x10...im looking at getting a great offset...i want to fill my fenders (20mm widefenders in front) and (50mm wide fenders in the rear) now with the sizing i chose what would be a good offset? i was thinking (+0 for the Rear) and about a (+15) for the front...what do you think...and another question. Is offset realitive to the center of the wheel or what...I.E. (+0 offset) mounting point on wheel being dead center? or where is the offsets realitive to on the wheel it self...just guessing becuase FWD offsets +38 ect...being that there is no lip and dont fit coilovers, that the mounting point is farther toward the outside of the wheel...correct? anywho...enough thinking for 5:30 AM...humor me...

correct, 0 offset is centered.

I don't know what offsets you'll need to fill out that widebody, a lot i would imagine.

Go zero in front and -15 rear. I don't have widebody, I am just going by how my wheels fit my car and trying to think if I had that much more fender to fill.

Thanks for the help

go into one of the old wheel size picture threads and choose a flushness that you like

use that wheel size as a base

plug the numbers into that online offset calculator app; screw around with the new widths/offsets until it extends 20mm front and 50mm rear.
