Fire,
Kevin is right, with foams a oneway is not needed.
Kevin,
There is a ride height rule at my track, 5mm, which is why I'm monster truckin' it
As for tire size, this was the starting size. I haven't checked them yet, but they should be around that size by now. I did notice the car getting faster per pack. You're right about the height with rubber tires. I ran it higher when running rubber. Like I said, this was my starting point, also, my first serious carpet set-up, so any pointers will be really appreciated .
Any one running the carpet upper deck?
What should I change on my set-up above if I was running that upper deck?
