Upgraded Spoiler For 2000 Boxster S

[Luv2Box]

I almost jumped on one of those years ago but posed a question about functionality to the PCA tech question and answer board on the PCA site. The answer I got is that the Boxster has an "air dam" not a spoiler. The large surface area has been engineered in to keep the car stable at speeds over 75 mph. It is doubtful that that spoiler can have the same affect, however, it would be cool if someone made one that fit on over the OEM one and maintained the "dam" part as I think it has a better look than the cheap OEM plastic piece.

OEM is actually a spoiler (also referred to as an air dam) who's job is to disrupt unfavorable air flow. This is a WING whos job is to provide downforce.

However, since this style of wing is used on the cayman, which has a similar shape, weight and weight distribution, it is conceivable that the use of the wing could be ok.

Assuming this wing actually does create downforce, the issue lies with the front/rear balance of the downforce at speed. The wing could generate more downforce than the front and cause the front end to go light.

I agree with most of what you say, however, the Boxster, being a convertible, would have different downforce characteristics with the top down than a Cayman with a sloping continuous hard top body, so perhaps the "wing" type spoiler would not exhibit the same downforce on a Boxster as it does a Cayman. Having a light loose front end at higher speeds is not what you want.

I agree without the smooth transition onto the back, there probably isn't much laminar flow. And there is a reason why the 987 boxster uses a spoiler but the cayman gets the wing

It would kinda cool if you could have both, the spoiler on top and the airdam under it as it came
