I have been told before that I am too fixed on the diffs and I know that is somewhat true
But I am like that. I kill that bird who took a dump on my 1:1 car. Like it spotless
It all began with me racing a xray t3 with balldiffs and I was impressed with the smoothness and the durability of it. I my world that balldiff was ace comming from racing buggies. A certain high ranked racer feelt it and shook his head. He rebuild it for me and the difference in the cars performance was stunning. So that transformed over to the buggies for me but I know it does not make that much of a difference there.
