I have a 2005 Honda Civic SI and I am wanting to put 1.5 inch wheel spacers and I cannot figure out what to buy. The hub is 2.5 inches

 

Why do you want to install wheel spacers on your car ? Why not simply purchase wheels that fit to your likeness ?

 

The reason is because spacers are about 100-150 bucks when new wheels are expensive. The second reason is because I love the wheels and tires I have for it. I just want the tire to come out an 1.5 inch basically to the edge of the wheel well.
