Pics of plugs. Need input. Car is a 2008 C6 Ls3 with minor Bolton's. Had tr55's in it, pulled them out and replaced with BR7Fe's. What do these plugs look like to you. YES I KNOW I shouldn't have sprayed on the tr55 plugs. Was on a 40n and 22f pills through Zex kit and cold bottle. Did A couple pulls on highway just to make sure kit was functioning. plugs have about 2000 miles on them also ran race gas the night I sprayed. Let me know your thoughts. I now have the br7fe's in and going to the 57n pill.
If I made a pass and pulled my plugs right after and they looked like that, I'd be saying WTF?
You have a rust color which I am going to assume that is the race fuel you were on. It looks overly rich too. Still, a plug shouldn't even look like the one in the pics after one pass. If it did, I'd be looking for motor damage.

looks like the plugs overheated, poss cracks in porcelain, and that ring around the base may very well be your initial hit from the fuel, before it went hot and cooked on. gap is too wide. because it was so hot hard to tell, but almost looks like over-timed too.
Because you have that fuel ring, I would put a cooler plug in, hit it again and see what it looks like.
of course, with appropriate spark and recommended jets by that company.
