hi ,,,

i have a STI '04 with 20k miles on it .. when shifting from 4th gear to 5th gear Near 6000 RPM the 5th gear start Squaking while you try to change it fast from 4th gear is this a factory issue ,,, Some say its a factory defect on all cars , is there anyway to fix it or to prevent it , i tried to Use the rev to get the 5th gear instead of the Clutch but its annoying in Street Races ,,, if there is no way to fix it i think im going to buy a Squential 6 gearbox , bout 6000 $ in ma country ...

Thanks ...
