Upgrade to 325mm rear disc size?

I have seen these and think they look like a good upgrade for the rear - what are peoples thoughts on them?

I have ordered the F56 JCW brake upgrade kit which comes with the 335x30mm drilled & slotted discs and also the JCW / Brembo 4 piston front brakes along with new chilli red rear callipers which use the same discs as currently fitted to the car.

I really want to upgrade the rear discs to a larger size as its disappointing MINI haven't increased them. I think these would look cool in conjunction with the new red calipers!

Ha - the kit only really upgrades the front, the rear from the kit is the same as the standard Cooper S!

No, I haven't ordered it yet - but have some pictures of it installed if you want to see?
