I have civiv ex turbo 17" wheels on my insight ex, I have 1" spacers behind them. It looks perfect, no rubbing. my mpg with mostly highway is 43, summer, 39 winter. Make sure you tighten the inner lugs often. I have had to retorque once a year and usually 1 wheel spacer is just a little too loose for my liking. mine is a 2019 I bought in 2018, so I am due again to check in the spring.
