I moved from Chicago to denver, well, my car did anyways. What needs to be changed to accomidate for the air/fuel ratio?

If I order a wings west body rs body kit painted the same color as my car, 91' crx si, in very good condition, will the paint color look noticably different? (sun fade)?

 

it would look different because of the fade

 

Have it painted locally, they'll match and if you want blend it with your stock paint. Will be more $$$ but will look better in the end. Remember you get what you pay for.
