Yeah, it is alot easier to loosen it if you have 17"s.

But I'm having a hard time adjusting the front one. It's so hard to spin it when spring is pressing it down. Wish it came with a tool that I can spin with.

The hardest thing when I raise or drop is getting the even space. I set the left(or right) rear one about inch higher than right(left) rear one to get an even height. Why are they so different?
It took me hour and half to get all four corners even.
