So, I used my new splitter at Thuderhill, worked well on Friday, Saturday, and half of the race on Sunday. Then in the middle of the race on Sunday, I went off at the back side of the hill at turn 5. The right side sheared the 1/4"x20 bolt but the left side held and bent the angle bracket, but tore the plywood off the carrage head bolts, but there's no damage to the nose of the car. So I guess it worked as planned.
