rear brake upgrade?

[wera racer]

I did the Salty Monk front brake upgrade (very nice) on my GS1000 and am wondering if there is a similar upgrade for the rear. Although the rear is rarely used when racing, the stock caliper and rotor are very heavy and it would be nice to put something smaller and lighter on it.
Thanks, guys!

Caliper from the later '80s bikes fits straight on - RG / GSXR etc

Thanks! And the rotor is a direct bolt on, too?

Not sure but probably. The caliper I'm on about is the one where the banjo fits on the side of the MC and was usually (always?) painted gold.
