how do you know what size spacers do you need and where can i get them?

 

What offset are you wheels?

 

once you answer mat's question you can get spacers from Onetongarage.com they are hub spacers tons of us on here run and vouce for they are only 10mm though so if your running a very high offset wheel you will want a bigger spacer..

 

it is given to me so i dont know...but it came of a 98 4dr civic

 

I have axis crux 19x8 with 45 in front and 35 in rear what spacers would i need if I wanted the rims to be super flush with the fenders?
