What im trying to do is map out my AS per hole in my ladder bars so im not just guessing.
Im currently at 122% and one hole up gives 147%, one more up gives 165%
Drag radials like to get hit hard, and you need a shock to keep it hit. I sent my shocks back to Santhuff to get revalved on the compression side

First I have no experience with drag radials. But as several have mentioned instant center of a ladder bar or a fourlink is just one part of the picture. A couple years ago I installed a new converter, and it lost 60 foot, my light got terrible, but it picked up MPH, got to be a good converter right? Wore out the fourlink holes trying to find a better sweet spot than I had. Moral of the story, a different converter fixed it. This spring I put a fresh engine in the car, lots more power, started spinning the tires, changed the link a little better, but not perfect, went to a softer spring and wow what a difference, it pulled a 1.28 60 foot, average before was 1.35 60 foot. If the instant center is at a reasonable position, look other places, don't waste all your efforts chasing something for no returns. Ask this old man how I know that?
