my previous std clutch ad bin in for 158k miles, only changed cos the box was out for a rebuild, but the friction plate/pressure plate finger where still like new only the release bearing had a bit of a grumble to it, and my disco has to earn a living towing cars around the country on me trailer + the many days spent green laning with no trouble whatsoever, I think you will only be paying an inflated price for something that you would never need. Most important to replace the clutch fork whilst doing the cluch assembly.
