I am considering fitting uprated and lowered springs to my 2004 XKR conv. which has the 20" wheels.
I would be interested in hearing from anyone who has fitted lowered springs and what the handling and ride are like afterwards
I don't have any info on the sublect, other than to point you to the Jag-lovers site where TC is asking about re-shimming the rear camber set-up due inner tread tyre wear.
Might be worth following the thread to see what comments come forth fom JL's
wide readership.
