X100 Rear camber bolt??
Hello All,
I have been told by multiple sources (Local Jaguar Dealership, Jaguar independent shop, etc.) that our camber in the rear can't be adjusted and I will need to swap out my springs, shock mounts and isolator pad to bring my car back in spec.
Do we really have a rear camber bolt we can adjust? If so, where is it and how is it used?
Does anyone have any experience with how much can be adjusted (Fractions of degrees or more?).
Thanks!

They go between the half-shaft rear axles and the differential output shaft - those two items are bolted together and the spacer/shim goes between the two... they are round spacers with four holes in them. There are instructions to do the job if you search... I ended up using my impact wrench and those 4 nuts are TIGHT the whole way.

If you refer to the picture of the (very nicely cleaned up!!!) rear suspension above, you can see that the lower arm is fixed in length, and the upper arm is the half shaft. With the diff output flange and the wheel hub carrier, these 4 make the sides of a trapezoid. You can make the camber of the wheel less negative (where the top of the tire is not so much tucked in the wheel well) by making the top of the trapezoid longer, in this case by adding shims to the half shaft.
Separately, double check the negative camber on the front as it is generally a sign that the upper shock mount is wearing out. This is a poorly designed part by Jaguar that tend to just wear out quicker than anybody wants. Excess negative camber = inner edge tire wear.

JaguarXKR,
Found this old thread, https://www.jaguarforums.com/forum/x...er-shims-6005/
Within, there’s a post by a fellow member ‘SpeedFerret’ who has added an attachment. It gives some helpful guidance on rear Camber adjustment. Basically, he discovered that a change of 0.5mm spacer thickness will change the rear Camber by 0.19 Degrees (Angle Decimal).
This ‘Spacer verses angle’ ratio will vary a little through the range of suspension travel (Due to unequal length Half-Shaft and Wishbones) but, it is certainly a good guide for you.
More importantly, what this does reveal, is that IF you have the factory spacers omitted (as motorcarman says, they are normally 4mm thick), then you will have a negative Camber of:-
-4.0mm = (8 x 0.19 deg) = -1.52 Degrees Camber
This is very close to the actual condition of your Camber results.
In summary, you need to get some 4mm Spacers because yours are suspiciously missing!!!

Agreed. Does anyone know what the specs for the later cars with the "handling pack" call for the rear camber setting? I believe that spec matches the Silverstone cars.
