Need your opinion on painting bumpers or not!

[calix5fan]

I have 3 options that I'm having trouble choosing between. I listed the options and concerns, what do you guys think is best?

Getting the aero kit and leaving the black plastic on the car - it's gonna cost around $2,000 and the main reason for getting this is to cover the black bumpers

Getting the aero kit and painting the bumpers space grey - gonna cost around $3,000 but might be unnecessary if I do option 3

Skipping the aero kit and painting ALL the black parts (the piece that running boards go over, the black strip on the side, bumpers) on the car space grey. I'd switch the grey kidney and bottom mesh to black to offset all the grey. Will cost around 1k but I don't know if this will look good. Anybody know how to photoshop this option?

Which option do you think is best?

Thanks !!
