Bike Rack for Model S

[jlucero]

i have a 2015 70D Model S with an unplugged rear diffuser. i live in the Los Angeles area.

Unplugged Performance Rear Under Spoiler and Diffuser System, unpainted

we got a yakima full swing rack for a 2 inch hitch that looks like this.

FullSwing

our plan is to hold 4 bikes on that rack.

i dont like the look of a hitch hole, so i was told that a stealth eco hitch is available where you can hide the hitch hole? is this true?

anyone know if a reputable installer in the Los Angeles area?

any advice would be greatly appreciated.

thank you.
