Stability Test...... while there is no specific test, I found my self pushing on the corner of the rear 1/4 panel. little or no movement. I leaned over the fender on both sides while changing and checking
oil. I didn't NOT attempt to shake aggressively nor sit on the car as I didn't find the need for that
The bars lock down into a position in which the weight of the car keeps it in this position. Of Course I was cautious!!! In this first attempt to use, I only changed to only; therefore only turning one nut! and the filter.
I need to inspect all other bolts headers etc as I am at my 1000 mile mark and break-in. So as we catch a warmer day, I will be back at it. I will try to take more pics!
I really don't think you can beat the convenience and compact size.
You can always supplement with jacks on the corners in you feel its necessary.
Happy New Year!!!!
