Best Late Model Setup Video or Books?

[jbtill12]

Has anyone used any of these books or videos for learning more about a late model? Have run mods for several years and want to learn more about late models. Want to attend the racewise school at larry shaws shop in January but not gonna be able to make it. Any comments on these or if you know anymore that are better would be helpful. Thanks

I think all of us have the GRT book. It is a little out dated. But if you are new to dirt late models, and 4 bars. The theory is still the same, and you can learn a lot. But it's not a book you can take a set up out of and go out and win.
