When you'd want to switch to 295mm AP Racing Brakediscs on the rear of your Elise or Exige, you will need to to more than use a simple aluminium spacer.
The mounting of the rear Brembo caliper is different, so the only way to be able to do this is by using special designed brackets.

This is exactly what we've done! These brackets simply replace the old brackets and will space the caliper out to be able to run the very much wanted 295mm brake discs.

These brackets can only be used on Aluminium Uprights (S1)
