@vtectom asked for the measurements of the APR Performance front splitter. The orange line (145cm) stretches to where it starts to curve in. On the outer edge it is pretty much straight from the orange line at the front to the blue line at the rear.
I havnt had it on the car yet but these are the pics that were sent to me against another Prelude:
@Merlin, did you take any pics from the sides? Wondered how much it sticks out on the sides looking head on and how far back those measurements meet with the wheel arch opening (from side view).
