I can't compare the Bilstein H1's with stock, because my stocks were shot in the back when I got the VX, and I swapped out all 4 at once.

I can, however, say that the VX is EXTREMELY responsive, and EXTREMELY stiff. with these shocks on. I'm 100% satisfied with them.

I keep taking corners a little harder to see if they'll give a little, but they don't. My feet stay planted firmly. I feel like I'm driving a big, heav sports car.

EDIT: Reg, I think you should try these babies on for size. They may shock you! (pun intended)
