Default Re: Inner fender louvers

There is several inches of space above the baffle brace... extending that up to about 1/4" from the fender is what is needed... The idea is to not allow air from around the tire to pass over the top of the baffle. When the air passes below the baffle it is at a relatively high velocity and the venturi effect occurs. Bitchin Products used to make extended baffle braces but they are out of business and no one else has picked them up.
