    I'm not rotor expert, but it would be very unusual to have a bigger rotor on the rear than front - the front brake is the one that does the majority of the stopping. You'll probably just end up locking your rear with a 203 rotor.

    I also think the general view on here is that floating rotors offer very little benefit.

    So theres no difference in stopping power?

    No, a lock is a lock with power a function of grip

    No difference in power between floating and non floating, no. There is a difference between smaller and larger rotors though and larger rotors deal with heat better.

    Why do you want such a big rotor on the back though? I wouldn't run anything that large on anything but a dedicated DH bike and even then with the new generation of DH brakes a 203mm can be a bit much even for my 100kg mass. Are you sure a stumpy can even take that size?

    Sorry lads got my ends mixed up front can take 200 max and rear 180 just that when i brake sometimes i pull the lever quite away in im pretty sure its not the brakes themselves as the've just been serviced and had new pads fitted i just want abit more bite will bigger rotors do this?

    More bite as in change where the lever bites in relation to the bars? No it won't change that unless the rotor is thicker but that's only because the pistons aren't adjusted properly. If you mean more power then yes a larger rotor will help with that but you'll get less modulation and increased weight.
