I'm trying to figure out what's different that make them more rigid also.
The inner fender skirt may be of a heavier gauge steel? Maybe bent in a manner that it's structural?
They claim you can use the inner fender skirts with the oem rad support with "minor" trimming.
I've seen the same product in a few other catalogs also. I can't really see what's improved.
