It gets pretty complicated sourcing the compatible outboard-braked rear suspension. The XJ-S used the old suspension layout for a couple of years past where the rest of the Jaguar line had changed to the new layout using a stamped lower control arm. For those odd years, they made new hub carriers with brackets to fit the outboard calipers, but the rest of the hub fit the old dog-bone lower control arms. Eventually, the XJ-S was renamed the XJS and there was a complete redesign to fit the new rear suspension that was common to the rest of the Jags.
