I can't help you with any measurement but, I can tell you that when I installed Konis on my 6, I noticed they also were nearly 2 inches longer than the oem shocks. I was assured by Koni that they would fit fine and there would be no bottoming out. I'm not lowered and I've had no issues whatsoever in 6 months on the Konis. Although, I do wish I'd taken photos and measurements for future reference.
