I built a brand new car this year, and my two top priorities were fires and tires. I made my firewall extra thick out of steel and it is totally welded 360 degrees around it to my floor, which is the same thickness. My rear partition between my trunk and interior is also sealed. My weak spot is around the pedals, but they are recessed behind the firewall. I went on McMaster and Carr's website, and they offer silicone seals that would do the trick. I used a sheet of high temp material w/high temp adhesive on the back side and cut it to fit the slots in my pedals, but it was super tough to get in place with out any cracks. They aren's totally tight, but as good as I could get them. On the tire side, I was running out of money but bought 18" Taylor Wheels and M/T 18" X 30" tires and run a spare set of 4-Ply 15" X 4 1/2" Funny Car fronts that are spares from past racing. Next step is looking at a Hans style device, but my cage is so tight that I don't think a Hans will fit..... Bottom line.....we need to police ourselves, to me safety is a personal thing, and I am prone to go a little overboard when running the speeds we run, especially when weight is not an issue like it is in drag racing.
