His split with them came weeks before the post, but he didn't put it out there very big. I heard about it through the grapevine before he posted that a few weeks ago, but he wanted to basically buy out controlling share of IPS and they couldn't/wouldn't come to terms that they agreed upon prior to him starting to manage it. Basically he did his part and they didn't own up to their end. This is also why you have seen the Vette FS and haven't seen it at any events the last few months....He's riding out what's left of his contract with them which expires this year on the Vette and then making a complete split I believe.
**This is what I have put together through the grapevine, this is NOT from the horses mouth....I apologize if any of it is false or misworded. No ill Intent is intended to Mark, I wish him the best.**
