Reptyl,
Yes they were not cheap. The kit consisted of two spacers to spread the caliper 10mm from memory. The hard part would be finding the discs. DBA may be able to help. or Mike M.
The discs may even be off a later model Jag.
Then again if you dont use the brakes and you have new tyres you might keep up with Garrett or at least gives us a good spin
Regards,
Phil
