ive read tons of ---- on brake swaps, (i dont like drums, hate/suck at working on them)

is it true you only need to swap the spindles out on the rear to swap in ls/rs/gsr rear disc setups? most people take the whole trailing arm and uca/rca to swap but the spindle i belive is just 4 torx and 1 bolt? then getting new/used calipers and rotors /braket is pretty easy, also i guess maybe the integra rear control arms /trailer arms changes the geometry in a civic

plus my back brakes are fucked anyways i dont want to waste money on drum parts
