thanks OH6A, thats good to know. 

you might notice the flexing when you lift up to work on. my scissor jack basically lifts car the same way and when it's up and i open door can't shut it tight until i lower it. i never leave the car raised. when i am done working on it for the day i always lower it.

that's where i set my lift pads to and have not had any problems. i might be overly cautious but it's me under the car so whenever i raise the car i lift it a couple feet off the ground and test for stability and then when it's all the way up i test again. even though i have had the lift for awhile now and i do trust it's lifting i'd rather be safe than sorry.

i am sure you will love the freedom your lift will give you to work comfortably

 Let me ask you guy this. to lift the car, I plan on using the same lift points that the GM manual suggests,  on the frame , behind the front wheels, and in front of the rear wheels.   Thats not going to change is it?
