I have a 96 xj12L that needs two new coil springs in the front, and the problem is they are discontinued or the aftermarket ones are wrong. So other than going to a junkyard to chance getting good springs, anyone know where to buy some?

 

I had the very same problem and this is the place I got the springs for my car:
Jaguar X300 Steering/Suspension/Bushes Parts

 

Sweet thank you very much!

 

How does one know if the coil springs are tired? Mine get very few miles (under 30) per year.

 

In my case the car had very low ride height which was making the car almost undrivable. After two attempts to get the proper springs the car drives great.
