Specialty Engineering does not have a website.
They have three mold profiles:
small bubble flares
big bubble flares
IMSA style box flares
They will make any of the bodywork for street cars (thick and durable), or race cars (lightweight and thin and kinda floppy, but for a race car, it's less weight!)
You might not be able to buy the IMSA units anymore, but they'd be expensive anyway even if you could...
here's a link to a few photos of the flares...
