so ive had the car for a couple of weeks and i took the car to the 1/8 track for the first time and gears wont go in at high rpms? what could that be? car has an exelent working 6 pluk cluth no slipping or anything and when daily driving gears go in perfect...but when im racing the car the gears are really hard to go in? any sugestions? clutch master cylider? slave cylinder? or bad syncros? bad tranny? ohh and its a ej2 with an 94 ls swap and ls tranny

 

I had the exact same problem as you, hard to get into gears at high rpm only. It was the pressure plate, do you have a competition pressure plate by any chance? because thats what mine was and i changed it out for ACT...problem fixed
