I'd say maybe 10k pounds max typically.
I think I want to avoid the C codes, they just seem too heavy. With C codes, why should I even bother changing from my OBS springs? I visited 2 yards yesterday that had B codes listed on Car-part.com. There had been confusion, because they all say that they have the B codes, but when I press them, multiple yards have made the statement that as long as I replace in pairs that it doesn't matter what code they are. I have argued that and at this point, pretty much want to see the door code myself before buying.
You are killing me with the talk about Fox 2.0s, and your advice is bad for my wallet Billy. Haha! Once I get the right springs installed, and maybe injectors, then my next purchase will be the shocks.
