Nice touch. They stand out very nice. I had the pinstripe added to the lower body line had considered the upper but after putting stripes on both spots decided I liked the lower better. I also had engine cover painted Toxic. My only problem with that is now I have to show the car for others to enjoy what I had done.
Here's a photo of show with my engine cover. Can't really see stripes unless your by the car or in right lighting, they don't show good on photo.

Here's one other show I did again engine cover shows well.

I really think Toxic looks great next to PCP, or any other color Challenger, first photo has Hemi and Toxic next to each other. Pinstripes don't show well in photos but they are there. Enjoy the ride.
