The 'info' says:
"The aerodynamically designed front spoiler reduces lift to the front axle and makes a powerfully dynamic statement. The inlet in the middle, here painted in black, further emphasises this sportiness. The spoiler made of an especially durable, high-quality plastic is primed and can be painted in the colour of your car."
"The roof edge spoiler not only looks good but is also effective. Its understated sporty look significantly enhances the tail end of the vehicle while simultaneously improving the aerodynamics. It is primed and can be painted to match the vehicle colour."
