I was over at Buttonwillow Raceway last weekend with my stock 96 Miata. Going around Offramp clockwise, I enter the turn in 2nd gear, but by the end of this increasing radius sweeper, I was hitting the rev limited. I tried to up shift to 3rd, but the shifter won't go into 3rd. It feels like something was blocking it from going in, but there was no grinding noise at all. I had to straighten the wheel out a bit to be able to shift. I ran into this problem every time so I had to change my line to get around this issue.
Why couldn't I shift when the car was corner at the limits? Is this a safety feature?
