Mazda RX8 sport front rotors - suit the rear of a SW20 with Delta-V dog bone adaptors.
I have a pair of used (though good) rotors to suit the rear of a SW20 with the Delta-V dog bone adaptors.
They are not warped or cracked, and don't have much wear.
Grab a bargain.
$40 for the pair. Pickup only in Sydney.
These are more than $200 new.
