Is 1/2" leaf spring relocation worth the trouble?

I thought I heard his street setup was a smaller tire, and his track pictures show a black wheel so he certainly has a different combination for that. But the article didn't mention it so I could have that wrong.

Funny thing is, when I was scrolling through the pictures I thought to myself; "those tires don't look any wider than what Blu runs". :D

Tire sizing can be funny too! Some 255's and 275's are very close in actual measured specs, I know there used to be some 305's that weren't all that much bigger than 295's. So there are definitely tires out there where the difference in the advertised size and the difference in the actual size aren't the same thing. And that's even comparing the "measured" specs, not accounting for a tire that's been mounted on a wheel that's smaller than the measuring wheel.
