I think its only a few inches, but I'd like to know for sure. If the idea of sunny side falls through then I will be going with these.. or maybe P11 sides since I hear they fit too.
The only thing you need to cut shorter is the shortest part of the skirt(rear part). Put the skirt up on the car and gauge how much you need to lob off. Think it was a few inches. The pain in the ass part of doing the 200sx skirts its shaping the rear part to clear the corner of the door.
