Anyone tried these discs?

Saw these whilst browsing the other day. Dont need replacements for another 5K or so but they looked interesting and although the S3/Cupra setup is good, i dont like the extra weight

They do the rears aswell. Seem a lot of pennies but it may be worth it.

I looked at these aswell awesome gti also sells these
I think it's a good idea if you want to keep the weight down, and also think these are only 1kg heavier then the standard gti discs so a win win
