If there are others out there, my indy didn't know about them. When I bought my mags to have them chromed, they didn't come with the rotor and my indy couldn't offer me any options other than to pick up a stock one somewhere and send it off and get it polished, so that's what I did. Somebody on this site sold me one and my indy got it polished up for me. On the rear rotor, my indy had a whole stack already polished and he did a swap price for me for one of those. Apparently there is a lot more interchange-ability on the rear rotors.

 

I guess there are no other options fo the front rotor, Like the Galfer but it looks like that's not an option.
