Autocross popping out of gear

[kivnul]

I have had an intermittent issue that reared its ugly head several times this weekend. I take a pretty sharp corner (with moderate to heavy braking before and at start of turn) in 2nd gear. I go to pin the throttle after turn exit and I am no longer in gear. I think its usually (always?) when I turn left. The transmission shifts fine otherwise. Could this be an issue somehow caused or made worse by having stock transmission and passenger engine mounts? I do have a Mountune RMM. I also have a Boomba ultimate shift kit so I suppose somehow that could be a cause due to engine movement. Thoughts?

Hmm. I do have a steel lathewerks shift knob as well. Its heavy and it would put some force on the transmission to shift into natural during a hard brake. I would think it wouldn't be enough to change gears when the engine is under a decel load. I'll put swapping it out on the back burner (it is locktited on.. loathe to remove it). Anyone have other thoughts?
