I've had both in hand (for the F2x/F3x), and the B8 has a shorter damper cartridge body. With the B6 front strut assembly, if you're lowered .5" it's already engaging the internal bump stop (which is kind of long and really soft). The B8 (and B14/16) has a shorter damper cartridge body so the piston has more travel before the outer strut housing engages the bump stop against it. Additionally the B8 bump stop is shorter and stiffer.

Here's a picture of the damper cartridge and bump stop in the B6 front strut:
