Hi all, I am thinking about making my own longitudinal lifting beams (similar to the "Liftbars" in the USA - BUT NOT exactly the same so as not to infringe any copyright issues !!!), to marry up with the standard jacking points. Has anyone worked out the location/dimension of the longitudinal centre of gravity for a 964, so I would have an idea of where to put a central boss on the bar - obviously the dimension would vary according to how much fuel there is in the petrol tank, so maybe a dimension based on a given quantity of fuel would help ie. 1/4 full, 1/2 full etc.
Hope someone can help with the dimension.
Regards, Les.

Unless you plan to lift both sides at once, I don't think the CG is important. The side being lifted needs to rotate atop the jack. Suggest you use pipe (because it is round) and then cut a curve out of a hockey puck to match the pipe. It'll rotate wee in that, plus lift it vertically all the time. See my thread under "alternative jacking point" https://rennlist.com/forums/964-foru...ing-point.html
ps - no infringement unless you plan to sell

I made some a few years ago. Used 2" 1/4" wall square tubing, with a 3" x 3" 1/2" metal square welded on each end to match the location of the jacking points. Glued some rubber on the squares.
Low profile jack fits under them. I raise the car in steps to get to the full height. Then place Work stands under the bars.
No problem lifting both sides at the same time
