Like the others I am sorry things didn't work out as planned for Greg and Ron. I can only speak about my experiences. I don't know Greg and started working with Ron about 3 years ago. I have attended all of Ron's seminars and found them to be immensely beneficial to my understanding how a car handles.
I asked Ron to take a look at my old suspension setup and put the numbers through his analysis software. He came back to me and gave me the hard truth that it wouldn't work for my expectations. He did tell me that I could make significant changes to make it better, but not to the level I wanted it to be at. I elected to cut my losses and move forward with one of his suspension designs.
The build process went pretty smoothly. It was about 3 months longer than originally planned but that worked out great for me. It allowed us to finish up with the metal work before changing out the suspension. The chassis shop also did not have the time to work on the car when it was scheduled to be delivered so the delay was actually good.
The components and service have been much better than I could have hoped for. Ron has been available to answer any tech or install questions that I or the shop has had. His service before and after the sale has exceeded my expectations.
I have not completed the car so I can't give you any feedback on how it is performing but I can say the race shop that installed the setup is pretty excited to see how it performs. They are expecting strong results.
Again, I am sorry things for others have not worked out as planned. I have been on the other side where I was on the short end of the stick. In fact, I am currently working with two different manufactures of flush mount glass for my car build and have been so for well over a year. I paid one of them for 1/2 the development costs of the glass and I purchased a car for the other one (to be used for development) in exchange for the flush glass. I did this to hedge myself and feel that I may never see a product from at least on of them. Like Greg I give the benefit of the doubt to people and sometimes I regret it. I don't regret working with Ron though.
I don't post on Lateral G much but here is a link to my build threat if anyone wants to see the car.
