Terry, here is what you are looking for.
PFC 2-piece non-motorsport (ones with the dimples)
Rotors "Starter" set which includes the entire setup (hat, hardware, rotor)
350.068.87 for the Left (cost ~$500)
350.068.88 for the Right (cost ~$500)
Then after that you just replace the rotor itself (comes with all hardware needed)
350.34.0060.87 (cost ~$300)
350.34.0060.88 (cost ~$300)
PFC 2-piece motorsport (ones with the gas slotting)
350.34.0060.07 left (cost ~$400)
350.34.0060.08 right (cost ~$400)
206.157.269.12 hat (same as non-motorsport hats and you need two) (cost ~$325/ea)
912.113.775.05 (bobbin kit....hardware) (cost ~$125/ea side)
re: the motorsport setup.....the main difference between (other than cost
) the rotors is that they are machined for the gas slots and named motorsport. They all start life as the same rotor it is just how they are finished. The hardware is different. They are AN fastners, which is an aerospace spec and are capable of much higher loads. The heads of the bolts are hex instead of allen-head but the nuts are the same. The bobbins are gapped differently to allow the rotor to float on the motorsport as well. While the non-motorsport ones are still 2-piece gems
they do NOT float.
FYI......I have both. Here are pics of what they look like.
