Rear brake upgrade

[Savgav1]

Hi guys. Has anyone fitted the rear brake 365mm upgrade from SF TUNING.
Just wondering if any pics and info as to what calipers these are and are they still single piston?

Wonder why they sell the calipers in the kit when all you really need are the discs and caliper brackets.

What caliper brackets are needed for bigger discs? contemplating for my T30. Thanks
