About £900 - £1000 all in. The calipers and discs came from a 3000 mile TTRS and set me back £750, you can get them cheaper, but these were from a revised 2013 model and are supposed to be less prone to warping like the earlier setup (whether this is true or not I have no idea!)
I then paid approx £200 to have them redone in the red with the Brembo stencil. As they are Brembo brakes, I thought it rude not to show them off

Fitting and bleeding them is a piece of cake and I did it myself, so the above does not take into account any labour charge.
