man i have never seen that one before... not much of a lip but sleak
i bought one and returned it immediately. its a big slab of heavy rubber and is a POS.
I highly suggest not bothering with it
I had to LOL at the "providing a sufficient amount of rear end down force to enhance high-speed stability "
This is what the piece of rubber looks like on my daily driver.
The double stick tape worked ok but had to reinforce it with some stainless screws to keep it in place.
And to say that it doesn't add any stability to the rear of the car is misinformed.
Along with the Mazda3 front lip that I added to the Paseo and this rear lip addition, have noticed increased stability at highway speed, and with heavy winds.
It does help stability and like it's design.
Yeah, it's not the prettiest piece but has a factory look that I like, and to me, enhances the car.
For me, it was money well spent , and an experiment that turned out good.
Btw, I've not modified it one bit and as you see it is as I got if from the manufacturer.

Thank you Dave and JBO! 
call me crazy but i think that would look retarded on a cav, the BMW M series trunk lids have a sharp, square edge. The Cav trunks are too round and there isnt a distinct line where the lip would go like on a bmw, it would just be kinda stuck on there.
just my .02$
