I'm using dynapro calipers 7816 pads and 160-12285 & 160-12286 rotors. Anyone know if there are alternative rotors for these?

Wilwood simply wants too much at 120 $ per side, I'm ok with 1 piece backups in the track trailer

 

There are no 1pc replacements.

However there are less cost options than the price point you reference above. Granted the quality of the 'ring' may not be the same but if saving money is the goal and you don't care about the directional casting, parallelism, balance and slots as much they can be had for as little as $35ea.

 

who makes 35 $ rings? and are there any cheaper hats?

I went with these, but for track use. I would like some cheap/light rotors for autocross

Being your MINI dealer..you won't pay retail like you would buying directly from Wilwood.
