I'll look around tomorrow. I'm not sure why the change. Wayne just handed them to me at a poker run and told me to swap them out. He said based on testing, I should be running the 45's...

If I recall they switched to the 45 angle around 2009 or give or take a year. I talked to Joe and Wayne about it and is was better tracking and tracking in the corners. If I recall they did say some added stability or plantness something of those words.

Brain has a pic from me as I took it back about 6 years ago and talk about it in person - the 45 angle on the trim tab.
