Question Front/rear alignment on a two post lift?

What visual clue do you use to align your car on your two post to ensure even weight distribution?

For example, on my other car having the side mirrors even with the posts seems to be best, but that is front engine model.

Is there a consensus?

You're in luck because I just created a C of G table based on various front and rear axle weights.

You are looking between 12.5 and 14 inches (depends of the above) ahead of the center of the rear jack point, the one closest to the rocker panel.

I don't care - with a 9000lb rated lift with very large baseplates, I think I can put the entire car on one pair of arms....

What I am saying is your lift should have enough safety margin so it does not really matter, as long as the arms hit the lift points, it should be safe. I find the positioning on my lift is more driven by the arm lengths than the weight distribution.

Besides that, you may be dropping an engine, and when you do that the weight distribution goes to hell anyways... :-)

Cheers,

Mike

Spot on information
A properly installed lift is very forgiving with these cars

Not rocket science... Though one could make it so

Great input guys - thanks. I have been known to over think things

14" or so does sound like a good starting point.

Next up is a shock/spring replacement, prolly from those hooligans over at FD . . .

The hard lines, not SS braided w/check valves

Yeah, dead 911s littering Westbound Hwy 4, sometimes all the way to my warehouse 30 miles away.

Accelerate - enjoyed your MaxJax thread, mucho good info - my install is not nearly as bullet proof as yours. But I guess it will have to do
