Wheel spacer size?

[Suspence89]

I'm going to lower my car which happens to be a 03 convertible and I wanted to buy a set of wheels spacers for my car. My rear wheel size is 10.5 inches in the tires I plan on using will be 315's.

I do not want my wheels and tires to be sticking out further than the fender. I want the rear wheel stance to be flush even with the fender well.

I have a lowering kit that I have yet to install and my friend suggested that I lower my car before I apply the rear wheel spacers because it will make a difference on the stance I guess that doesn't make sense to me but that is what I heard.

So basically what size wheel spacer should I use to make my rear wheels flush even with the fender well with a 10 1/2 inch wide wheel with a 315 tire???


thank you Spencer

What is the wheel offset? Without that it's impossible to know.

What do you mean by offset?

The rear wheels would be either 17"x10.5 or 18"x10

Lower the car. Then measure from the lip of the wheel
to where you want the lip of the wheel to be and that is the thickness of spacer you want.
