Hi Hurricane, great job on the corner weight, you nailed it, curious why you picked up 200 lbs between readings though, I suppose to show how much difference you sitting in it makes? You don't need adjustable sway links, but I assume you did your cross weight with the bar disconnected, at the frame or the arm is OK. We want to know if they are putting any influence into the numbers, if over 15lbs then neutralize them with shims or slots at the frame should you not want to buy the adjustable links. As a general rule, if a street car can cross weight under 100 lbs, thats close enough to not kill anybody. IE: pretty normal. For a race car 20 lbs is about the edge of the box. I noticed also you were going to drop the rear a 1/4 of an inch, which I think you should try. Do not be surprised if your result is different from what makes sense. Reasons: you get the weight shift yes, a good thing, maybe 30 lbs, you also change the relationship of the roll centers for the front and rear, ie front and rear relationships are now a little different than they were along with toe curves etc, but doubt that it will be enuf to unravel your confidence in an increasing radius. One last thing on that, Vipers like some attitude, ie rake, the way it pushes through the air with a bit of nose down keeps it glued a bit better above 80 mph. Can you drop both ends and still keep enug susp travel?
