I've been all over this forum, and google trying to find the hub size for a 99 civic? Trying to avoid putting a hub centering ring on if at all possible.
If anyone has all the measurements of stock wheel, that would be great.

4 X 100 X (stock offset) X (Hub Size).

 

Looks like I finally answered it myself. They have a 35mm offset, and a 56.1mm bore. Hard finding wheels that are hubcentric. Likely need to go with hub rings.
