Hey... iwas wondering is it okay to change only clutch without replacing the flywheel... like grind the old flywheel
And does the elantra sport 2017 DCT have dual mass flywheel or not?

Yes, the clutch pack can be replaced, but I'd replace the pressure plate as well. Keep in mind that special tools and GDS is required.
Flywheel is dual mass.
