Having qualified fastest at the season-opening race at Phillip Island, Rea was looking to make it two in a row at the Chang International Circuit and he did just that.
The Briton posted a circuit record time of 1:33.382 to see him just stave off the challenge of Leon Haslam's Aprillia.
Speaking after Superpole, Rea revealed that he had been struggling at Turn Four on the circuit and that this was initially hindering him before he was able to get everything right and put a complete lap together.
“It’s good to make it two out of two. We know the Kawasaki really takes profit from a soft tyre, especially the qualifier," he said.
"My pace has been really strong all weekend in race conditions so I knew just to make clean laps in Superpole. But in every lap I made a mistake in T4 – the fast left – so I ended up much too fast and the rear came round, which is a problem I have been working on a little bit.
"We found some things after we struggled with my back brake at times but we fixed it in this final session. I was able to enter T5 much better. I made a mistake in T1 on the first flying lap and then I saw the time was P1, so I knew not to push too much and just make a clean lap next time.
"I saw a 1’33.3 near the end of the session and I thought it may not be enough, so I tried again on the third lap with a qualifier, but already the tyre had had enough.”
