As I have upgraded the front brakes with 320mm discs and Renault 4 pot brembo`s I thought it was about time I upgraded the rears.
Now I could go down the route of Porsche 4 pot rears but I`ve gone down the route of a set of these,

A set of very hardly used XC90 308mm discs and calipers,
All I have to do is to make a bracket to mount the XC90 calipers to the 850 caliper mounting point :)
