Spoilers have to be a balance front to rear. The R has better down force so the front was changed also. That is the reason I questioned the downforce of the track pack spoilerYes it does, it provides signifigant more down force than the base spoiler. And the R has more down force than the track pack
I actually would be willing to bet it's not unreasonable although for normal drivers, not a make or break. Try sticking your hand straight out of your window at 100MPH and then slightly angle your hand downward like a spoiler would. She goin' down. Fast. The slope of the spoiler is pretty pronounced and the slope runs the entire length of the assembly. It also matches the contour of the rear.I wont pretend to be an expert but, I don't see it doing a lot over the base spoiler but, it looks good
