The braking balance is better with 262mm discs. But the 262mm discs crack very often as I know.
One good brand is the brembo MAX discs for 262mm discs

and the same discs after hard use of 90000 kilometres still good

If you want an overall brake upgrade it is wise to swap 282mm discs on the front and 260 discs at the rear axle with a bigger master cylinder and servo (brake booster). With these mods the braking will be much better and the balance corrent between axles. Oh if you have ABS you will need the EK4 proportioning valve to work better the modification
