That is correct ! The 87 and later hubs are different and the disc mounts over the top of the hub. This setup allows you to use the original Porsche bearings . I can supply these hubs. They are beadblasted and we also drill the dustcap for the beetle speedo. The sleeve dimensions will not allow the pre 87 hubs in this kit . We are currently working on that option.
The rotors we supply in the kit are 280mm. They can be gas slotted if you like . The rotors are 28mm thick. I can assure those doing this conversion does give great breaking with the big 4 pot calipers. I am running the standard 19mm master cylinder with mine . The pedal pressure is great! No need for anything bigger. When you hit the pedal it makes you think .. Wow! I need racing harnesses! It really is worth the effort! [I]Its like riding a 12 second street car in reverse !:silly:
