Optional Brake Disks?

[RC-Monster Mike]

The brake disc kits I will offer will fit the included out drives. Most 6mm diff out drives should work in the Slipperential anyways, so you could most likely install the diff out drives from your existing diff and use the disc brakes from the kit as well.
Note - "most likely" - I obviously haven't fitted all the major out drives to verify fit, but the diff out drive is a pretty standard diff out drive, so a HB, Kyosho, AE or Ofna diff out drive will most likely work. :)
