We must be brothers. Haha I got it aligned when I did the tires. I replaced everything you could think of up front. I still have a knock if I’m hard on brakes or going from r to d. It’s only in the front driver side. Weird. I still have the back to do but they don’t make B6s for my rear since I have bags with the 3rd row. The B6s are only harsh-ish in construction zones but I’m thinking about swapping the B6s for fsd when I do the rear shocks, arms and links. I have other issues atm (low pressure underboost) so I’ll have to wait on the rears.
Op, I have no regrets about the B6s and ultimately decided on them over the konis because of brand and longevity. With no options for the rear, I may swap them to see if I like the konis rather than a hard front and softer rear suspension. I just think it would feel weird and should have done more homework before I got the B6s. So make sure you can get what you want with your setup (if you have 3rd row), before you decide.
