Just installed them last weekend. Observations:
Very nice quality.
Easy to install. Poor written description but good pictures (included) are all you need.
No problems with fit. Easily clears wheel pants and no interference with brakes.
Makes torquing easier (no socket access with original).
Tested fine with my travel scissor jack (2.2lb aluminum vintage porsche).
Hope to never use them as I have 2 nice wing jacks at the hanger. But, leaving on a 48 state trip soon and they check one of my boxes for travel maintenance.
