Central Jacking Points
#21
Good luck...I have not found drive ons that will clear the low air dam.
Don...I have kept my car for 11 years, and have no intention of selling it in the next 11. I assure you all my seams will be just fine! You will also note that the balance point for the jag is within inches of the front jack points, so there is very little twist placed on the body from that point. The manual was written by engineers who were developing a body using techniques that were new to the industry and they were really not sure if it was going to work long term. I know from experience that the design and bonds are working just fine.
Something to think about...when I jack from one point, the suspension floats the other 3 points of the car, so the twist is buffered. When you jack using 2 jacks, you are using 2 hard points, and since they cannot be jacked absolutely evenly, the hard point, uneven jacking puts as much stress on the body as my way. You see, I went through this thought process 11 years ago, and decided to jack the way I have been jacking that long ago. As I said...I have had the car on the frame machine multiple times, and taken multiple hits from jackasses running red lights...and my car is just fine.
Take it or leave it...I just provide the information to be used or ignored.

Re. your remark on suspension floats, that's a good observation.
Raising as evenly as possible with two lifts will however allow to minimise the twist

I have an older set of plastic ramps and a newer set of Rhinoramps, and they work fine on our XJR with no scraping of the air dam. If your air dam is lower than the one on our car, or if your front suspension is sagging, just add a scrap of 1X4 or 2X4 lumber ahead of the ramp to raise the front end of the car as it ascends the ramp (I do that for our BMW, which has an M air dam). The Rhinoramps are about USD $40.00 from many sources here in the U.S., including Walmart. I would be surprised if similar ramps are not available on other continents:
Cheers,
Don
