I purchased a 96 XJ6 a few months ago. The tires were bald and the shocks were beyond terrible. I replaced the tires and the car drove nicely. I had a wheel alignment done a few days later and the car drove much much better. Then I fought for four days replacing the shocks (thankfully I had some Jack Daniel available). The rear ones were fun to change if you know what I mean. The car finally started to handle like a Jaguar but not like my 95 XJS. Now two months later the shocks are broken in (who knows maybe there is still some breaking in left!) and the car handles amazingly well, almost as nicely as my XJ6. These Bilstein shocks are very impressive. Of course it takes a Jaguar to bring the shocks to their potential. I am really sold on Bilstein.
