I have a 18 Elantra GT Sport. I didn't use Shark Racing's short shifter I went with Hyundai's short shifter for a 2019 Veloster R. I'm sure they are similar. I like it a lot, shorter shifts and much better feel. I also had Sxth's shifter bushing's and shifter cable end bushing's installed. If your GT isn't a Sport I think the shift knob can't be used because it's not threaded.
