Cadillac STS Forum - 2005 through 2010Forum for discussions regarding the new Sigma-based STS model. Not for Cadillac "Seville" discussions (2004 and older).
I just bought sts 08 Wing or Spoiler. It looks grrrreeeaaatt. Just a discussion on a side note. Does the wing improve any performance on the car or is it just for looks?
The spoiler is to disrupt airflow and exert downward pressure, thus keeping car to the road. This being said, you probably won't drive fast enough for this to make a difference (then again - maybe you will). Mostly for looks.
