My Wheeldock stand is pretty much a flush install at the lift points I use to lift the bike. I just went out and tried my lift and it works perfectly. To me it was more difficult aligning the lift (without getting on the floor) with it on the center stand, so I believe I’ll be on the jiffy stand when lifting.
The web site says to lift the rear tire off the ground, place a ¾ inch piece of plywood under the stand. Not sure about the front tire. I’ve been using the lift to wash my bike and lifting slightly higher for the wheels to clear the ground when actually washing the tires and rims.
