Do you have a "torque arm" or whatever you want to call it to keep the motor from rocking? This one is a threaded rod with heim joints at each end and a tube over the rod just for looks. Sometimes when we have to shift to third, I've been known to hit fifth :-( We have a fifth gear lock out...
We never go beyond one turn of the steering wheel on course. With a stock Miata power steering rack. You just have to remember to not go full lock moving around paddock, etc.
