Rear caliper options

Hi all, new to the TRX as I have only just bought it. Stripping it back I now have all of the suspension linkage stripped, cleaned, greased and back together. Forks (Thundercat) drained, cleaned, new oil and seals, got a pair of Bluespots to fit but I don't think the rear caliper is up to much. Are there any other rear calipers that bolt onto the original rear caliper holder or a different holder and caliper that fits with the original torque arm? I was wondering if any of the Bluespot rear calipers are a direct fit. Thanks for reading and hopefully somebody has done a swap out in the past?

ThunderAce caliper is direct replacement for original.

I used a 220mm early YZ125 rear disc which is the same bolt pattern and a GSXR rear Caliper and Mount. Had to sleeve the axle hole from 28 to 20mm plus shave about 1mm from the mount where the Caliper bolts on for alignment. Mounts underneath so torque arm mounting is no issue.
I also have reworked Thundercat forks and had the orifice style cartridges removed and retrofitted MT/GSXR shim stack cartridges to improve damping response.
