I've been thinking about getting an S281 spoiler for my car does it reduce aerodynamic drag lower than what my stock OEM spoiler or am I better off just leaving it alone. The S281 sits flat along the trunk lid and scoops up slightly while completly sealed from air getting underneath, where as the Oem alows air over and under the spoiler just google Mustang S281 spoiler for 1999-2004. It would cost me about $200 for the spoiler but I have to get it prepped and painted yet, But my car is due for a new paint job next spring because it's got quite a few knicks in the paint from the previous owner. It's currently silver but am probably going to get it painted Sapphire blue or Subaru blue. any opinios here? thanks guys.
