45 minutes?!? Wow, that's fast. I once changed all four sets of brake pads on my '79 Volvo 244 in an hour, but this is something else entirely... nice work!
PS... Peewog and I drove each other's VXs last night - hers with OEM shocks and mine with the the Bilsteins - and I can report that the Bilsteins provide about 98% of the damping that the OEM shocks do. I thought mine transmitted road surface imperfections a bit more than hers, but I'm chalking that up to different tires rather than the shocks. Bump, rebound, and body motions were nearly identical with either shock. I'll post more details in the other thread.
