I got a couple of attachments made that sit on top of the jack head to lock the jack into the chassis rail. Work a treat.
But in testing these I noticed again a disturbing (to me anyway) thing that happens. As the car is raised the jack tilts towards the opposite side of the car. You can see it in the picture below where the base of the jack is off the ground. The leaning to the right is just my bad photography:angel:
I'm not an engineer but I assume this has to do with the height of the car when jacked up, which in turn means the car is levered over to the side opposite that being jacked.
I assume this is normal but it just looks weird.
