I purchased these a few years back but never needed them in the end as my Godspeed Discs came with the spacers to fit the MK3 Caliper. I understand the kit includes the following; 4 x 12.9 high tensile 12mm Allen key bolts 4 x steel washers turned down to fit Brembo bolt insert 4 x full length alloy custom brackets 2 x alloy spigot rings 60.1-66.1mm £200 posted or Offers (can’t remember how much they were but they a nice bit of kit).
