It was right ( or closer) the first time before you changed it. ( if that old mod guy changed it, tell him when he knows the difference between a splitter and a spoiler too, he can change it, but until then ,...shut the hell up)
* Taken from CJ pony parts:
Chin spoilers are sometimes called front spoilers or air dams. These parts are also sometimes added purely for aesthetic value, but, like spoilers, they do serve a purpose. Underneath your car is a topographical map of valleys and mountains that catches air, creating drag and lift. A front air dam prevents that. By decreasing drag and increasing downforce, the chin spoiler provides an easy performance boost in handling. As an added benefit, the increased airflow can help to keep your engine a little cooler.
FRONT SPLITTERS
Splitters are attached to the front of the car and look like a flat scoop. Because the downforce on splitters can be intense, they’re often supported by small metal support rods. The splitter actually works as a wedge, sending the low-speed, high-pressure air over the car and the high-speed, low-pressure air underneath the car. The overall effect? Reduced lift and subsequently increased front tire traction. Resulting in increased grip in high speed turning situations.
One of the most famous splitters for Mustangs is the iconic front splitter printed with “Shelby” but there are plenty of great splitters available for every Mustang, whether you’re driving a Shelby or an Ecoboost
