Aftermarket 660Z Rear Brake Disk

[Blitsie]

Since my rear disk decided it's time to go on 26 000km, what is a good aftermarket option to fit in the attempt to get away from the dealer prices? Is there a offroad disk which fits as there is ample aftermarket parts available for offroads. Advise would be appreciated then I do not have to go to a shop this weekend with a sample and search for something.
