curious to see if this mod makes a difference(you would know). I understand the theory, but that ½" doesnt seem like much.
I too wondered if it really makes a difference with modern lowering springs and other suspension improvements I've done. I talked to Harry Quackenboss who was Herb Adams chassis engineer back in the SCCA days when they came up with the mod. He said that the modification still makes sense. I will be hard to tell if it does anything because I'm making so many changes to the car's setup at the same time. If I pulled the pockets and made the mod with no other changes I might (?) be able to tell a difference. But with the mod combined with spherical bushings, larger diameter wheels, narrower tires, less weight, and a lot of aerodynamic changes the effect of the Adams Mod will get lost.
I did get the pockets painted and the gas tank which will also function as the roof of the diffuser if my plans work out.
