Fire jacket?

I've been doing some reading and found that some tracks require a SFI 3.2a/1 fire jacket at 11.99, as opposed to the NHRA rule for 11.49, but I couldn't find any specific tracks. Has anyone been to a track where that is the case? Are there any tracks that enforce the roll bar rule at 11.99?

I'm expecting to get well into the 11s this year with the upgrades I installed this spring and want to be safe, but I'm not real keen on wearing a jacket in the dead of summer unless I need to.

I've been looking at fire jackets as well, any recommendations? I found this jacket on Pit Stop USA. Anyone have any experience with Pit Stop USA or Velocity Race Gear equipment?

Thanks.
