I dont have drilled/groved disks myself but yes these would fit. Standard Altea TDi 140s are 288mm/255mm. new FRs are 312mm/286mm
I put 312mm on mine at front and still toying with 286mm on the back, though its a bit more work to upgrade the back ones...
if you give David (seremotors) a pm and give him your VIN number he can check on ETKA the correct size that was fitted as standard to you car at birth
