I had noticed that my Jaguar didn't seem to grip as well on corners which bend to the right versus ones which bend to the left. So I had the dealer re-do the alignment and was still not satisfied.

Apparently Jaguar uses the camber settings to offset the camber of the road. The settings are so aggressive in fact that the car noticeably seems to have more grip cornering to the left than to the right.

As a performance oriented driver, I began to get frustrated with the imbalance in the cornering ability (left vs. right) and so took it to a specialist performance alignment place to re-do the alignment a second time. These guys aligned the car with me in the drivers seat to get an optimal performance oriented setting.

Cornering ability is now amazing in all directions. Also I found the Jaguar techs were not as precise as these other guys so that has also improved the sharpness of the steering response and the on-center feel.

 

Care to share your settings? I know someone posted stock settings here before. I'd love to see how much they differ.

 

nice, info. do you have the specs that your car was aligned to?

 

see attached.

 

Seems to me that Jaguar has a pretty large "specified range". All your before numbers were still in spec, and so are your actual numbers.

 

Yes that is correct. The main difference is that the before numbers which were the product of the dealers work a week ago did not involve camber balance. It seems to make a meaningful difference.

You will notice the front left and front right range are off.

 

So what you're saying is that Jaguar is setting camber specific to whether the car is bound for a left hand or right hand drive market? Sounds unlikely. They're making a road car, not a NASCAR.

 

Yeah, it does look strange that "in spec" could have such a different value for right and left. One would think that having right and left to be semi important, which it sounds like from your original post, does make a noticeable difference.

 

I think this is true, because I have read elsewhere on these forums someone imported a Jaguar from to a RHD country from a LHD country and the alignment shop used the wrong specs. Apparently the specs are different (possibly reversed) for RHD and LHD. Perhaps they are accounting for the extra (average) weight of the driver on one side of the car and assume no passenger...

 

That's exactly what I am saying and if you search these forums you will find that it is well known that Jaguar does this. There was even one guy whose US Spec car was accidentally set with the UK settings.

 

That's what I am asserting.

I am also certain that BMW M does not have these different left and right settings. Not sure why Jaguar thinks it's a good idea and BMW doesn't but I am inclined to think BMW M knows what they are doing better!

 

Even NASCRAP gets it right twice a year when they run road courses...
