I have an early 2006 XKR (X!00). I need front shocks. How can I tell if I have the "performance package" or not? I do have 19" wheels, brembo brakes. And I know I have the "adaptive damping control.
I see a part no for 'w/o perf package but with the ADC' system of MJB2140EC and a part number for 'w/ perf package' of MDX2140AB. How can I tell which I have?

 

I would suggest removing the cap over the front shock tower. If you have wires going to center of shock, you probably have the more expensive adaptive system. That is what I have on my 2002 xkr. I would assume the same on the newer model. good luck
