lets face it, a majority of people do the conversion more for the looks, and the fact it brings the old methods used on the rear up to date

i can honestly say i have a 4x4 cossie rear set up for mine, and im under no illusion that its pointless performance wise if it has to be wound in using a bias valve in order to bring it down to a level more suited to whatever the front setup is capable of. but mine came for free, and i figure it will look nice, so why not lol

lots of opinions out there on rear disc conversions and bias valves and such, lots of people think shouting and using exclaimation marks makes their theory and method correct aswel

depends what u want them for, what u wana spend, and who u choose to listen to
