Moved to the Gen1 area.
I'm not aware of any kit.
As much as we appreciate your 'gift' to your CR-V, what you propose isn't really worth it in terms of brake performance on an otherwise 'stock' car.
You are better off doing regular (yearly) brake shoe adjustments, and lubrication of the shoe-to-backing-plate contact area.
You would be surprised how well the car stops just from doing this little bit of maintenance, as it gets those rear brakes to do their share of stopping. A friend actually COMPLAINED that his '04 Civic 'stopped too well' after I optimized his rear drum action.
