Current disk and pad prices (aftermarket)

What the equivalent brake disk and pads for these cars, without paying silly Renault prices?

Cheaper and not at all fit for purpose.
There currently is only Borg & Beck and they are not manufactured correctly and do not fit the car properly. You will waste your money.
I’m sure as Renault releases it’s grip and South Korea starts manufacturing larger quantities there will be some in the future, for now its Renault OEM.
It’s a shame Nissan didn’t expand ‘their’ mobility car. It was a twizy with a Nissan batch glued on the front.

I found a few BAM and decent makes like Ferodo,

Have you tried many ?
