Does the JCW or any of the aftermarket rear spoilers / wings help reduce the amount of dirt and dust that gets on the back window and bumper?

 

Yes, they actually direct the air DOWN, against window, as opposed to the standard spoiler. As you know the dirt on the rear window comes up from the road.

An SE would look awesome with a JCW spoiler. Would complement the front chin spoiler!!

 

Yes, the JCW spoiler does keep the rear much cleaner than the standard spoiler. I know because we have a JCW and an SE and the rear of the JCW stays clean while the SE is always dirty.

 

I have a JCW and if this is cleaner, I would hate to see dirty. My hatch and back widow are ALWAYS the dirtiest part of my car. The rest will look OK and the hatch will look like I just drove down 5 miles of dirt road 😂😂😂
