So when i was at the drag strip a few weeks back 2 of my runs it would lock me out of 2nd and one of those times i was locked out of 4th but would eventually go back into gear. I have an ACT street disc clutch i hear these can cause gear lock outs. have any of you guys experienced this before? It only did it on the drag strip its never done that anywhere else before...

 

There have been many incidents of ACT clutches locking out at high RPM and I'm assuming you're experiencing the same issue.
I used to have one on my Evo 8 some time ago and it never locked out even at 7500 RPM, which leads me to think it's more of an installation issue than a product issue; however, with the masses complaining about the lock outs, I guess I was just lucky.

 

Adjust your clutch pedal. Its no longer a mystery why this happens.

 

Thanks for the help guys.
