If you have the ability to rip it down to 1-5/8", then I'd recommend that. It is better to simulate as much as possible the track that the car will end up racing on. That will make tuning easier.bloard wrote:So, I need to ask my original question again. Am I really going to lose much testing validity by going with the 1-3/8 rather than ripping the 1-3/4 besides the possibility of my rear wheels touching on a real track?
With thinner latice, you may see more energy lost when hitting the rail and more radical changes of course.
