hey guys, i've searched this question but people have said 12x1.25 and 12x1.5.

it's an Si, if that matters..

so does anyone know the definitive answer? i'm asking because i will be ordering some lug nuts soon.

 

I'm going to assume the FAQ is correct, as that was the correct size for my 2000 GSR, but I can't speak for certain for the current Civic.

 

ahh thanks for that. i should have looked there first. my apologies

 

it is 12x1.5
