[Supras] Colder plugs, when do yall use them?

[Walker, Brian (Rich. Dist)]

I've tried a range colder (I run 2330, so I believe 6097 was the colder
version) I didn't like them for normal around town use. I am however
thinking they may be a better suited plug for road course use than the
stock range. Have others used these mainly for race use? At my last
event I had old plugs in and boost turned back. The car had no power
above 4.5k. I was thinking a colder plug might do much better even when
it's been left in too long.
