I live in Arizona were I'll bet it get's hotter than D4. I was at a National event, passed tech with my AF/S Shelby when later on Danny Gracia (Nat'l Tech Director) walked up and said he would let me race as soon as I cleared off the tinting. So I grabbed a razor and some windex and off it went! Mind you, not without a little disgruntlement under my breath, but he's the man!
The reason they don't like tint is it makes it harder to see what the driver may be up to. That would usually mean "no good".
