I'm just a club level racer from over the pond in Oz and I was fortunate enough to come across these forums and the information that Ron gave in the suspension threads which helped me better understand and setup my race car.(This was a great help and it was free)
After attending the course in 2016 and learning a whole bunch I decided to contact Ron to look at improving the setup and handling of my car. I will admit at this point that the initial time frames proposed were pushed back a few times, as it seems that my job fell into that year range he put up in his post. For me that was no real issue, I was still racing my car and wasn't waiting desperately. However, once it was all done and sorted, I came to the following years workshop and got my parts at the same time and took as much back with me to Oz as I could pack in my bags. To be honest, to date, I haven't done all the modifications outlined, mostly due to a lack of time to implement them(It is hard to stop racing to do upgrades). The modifications that I have done so far have all netted big improvements with no issues. I got all the parts that I paid for and all the services too. I can say that there were no negatives to the overall experience other then the time it took to start it all.
It is great to see a response to this situation. Who knows whether it will clear the air or just stir more ****, but something is better then nothing and it is an open forum for all to speak/converse from all sides. Best of luck to everyone and I hope Greg does get the car finished how he wants it and actually gives it a fang around the track! We are all here because of racing, its what turns the world around....atleast for us motorsport orientated people anyway
