I had Coleman Machine (or google up Coleman Racing) make me a custom set for my STi for half the price of PF.
The rings were around $120ish each and they were heat treated and lasted me forever (wear induced replacement vs cracks).
You would need to send them the stock rotors once. They will design it for you and send the new kit. Moving forward, all you have to do is call and they will ship the rings vs sending them the specs again.
They do rotors for NASCAR and Prodrive in the US so rest assured you'll be safe for DD
