Wheel alignment done, I gave the guys the GT specs and asked for that or as close as possible.
So this is what they got me;
I honestly didn't expect they would be able to get -1.2º camber out of it, let alone -1.26º
It's raining here again so haven't literally driven it around the block and no further, so i'll have to update some more once I have some time behind the wheel.
The E-Diff in the XKR-S GT used the F-Type calibration, one of our gurus figured out a way to load that calibration into the XKR & regular XKR-S, it's also possible in the XFR / XF-Supercharged and the XJ SuperSport / XJR.
I drove a 600hp tuned XKR this week, that had been loaded with that software in the E-Diff. And it's just, wow....
Basically instead of controlled slip it just locks the rear axles together, feels very much like an old-school mechanical clutch plate LSD. It locks instantly at the first hint of wheelspin.
This means it also won't overheat the diff during track work, which was an issue with these things, because they slipped, not locked, the increased heat from the slipping of the clutch plates was the problem.
Some tests (on the street) with Dragy saw the 0-100kmh / 0-60mph times drop about 0.25s on average with this software loaded.

So, you tease us with a tidbit and don't let us know HOW to do this????
What's the point in saying this without saying how to have it. You're like the hottest girl in high school wearing the sexiest and least amount of clothing possible.
Seems pretty straightforward there fella's, find yourself a jaguar guru, have said person then acquire the XKR-S GT calibration and load it into your car.
Found something interesting about the front vertical links "steering knuckles" in one of the technical manuals...
NOTE: XKR-S vehicles use specially designed wheel knuckles that provide increased camber and castor stiffness to improve the accuracy and weighting of the steering for greater levels of feedback and precision.
According to the technical blurb these are 30% heavier than the standard ones, but they really aren't heavy anyway. Can easily pick one up in your hand with the hub removed. I'd say the hubs are actually heavier than the vertical links.

How does one go about uploading the E-Diff software for the XKR-S GT? I would much prefer a mechanical LSD feel to the car under load. Plus it would make elevens much more evenly.
