Difficult to engage 1st, 2nd, and reverse gears.

I am experiencing similar issues, replaced clutch, flywheel, throw out bearing with a stage two ecs kit. Clutch seems to stick at engagement point and i’ve brought it too the dealership and they can’t recreate. i’ve had multiple people drive it and cannot recreate it, ive convinced myself i don’t know how too drive manual because of this but i can drive other manual cars with ease and it’s really starting to anger me
