I installed them last night on the car, and put the car on jackstands resting on these. Since I was jacking front and rear individually the end opposite of where I was jacking would move ever so slightly due to the fact that a standard floor jack moves front and rear while going up and down. When I saw it moving around on those my butthole tightened up considerably so I removed them. They’re not designed for jackstands, only for the wide pads of 2 post lifts that go strictly vertical.
But, they’re easy to install and supposedly cut down on wind noise at speed. See below for a good thread showing their installation and use. You can somewhat visualize in the last few pics how a jackstand doesn’t have a lot of surface area to hold on to.
On a side note this makes me want a lift even more in the garage. I’m getting sick and tired of the constant shuffle with jackstands and floor jack. I initially was settled on a 2 post but my biggest limiting factor is the floor space, and a 2 post would have made my 2 car just absurd to walk around in with cars in it. I still want to use the garage as parking space when not wrenching. I am thinking of a recessed dual scissor lift…need to do some more research on brands and installation but it seems like the right solution for my application.
Fuck yeah…I cut the exhaust off last night to begin planning the new one. I thought it was loud blowing through 2 OEM cats and an open cutout, boy am I glad I deleted those. She loud now.
