Also, I don't think you'll be driving that car on the streets anymore, so why not pull out anything associated with the audio system and do some weight savings?

I cut the exhaust off right before the can. I also have a stock exhaust for around town. I have a radio and other comforts so that I can drive to the track. I don't like towing and would argue that it's safer driving this car than my tow rig. The bars are well padded and a long way from my head. The B-Spec weight is 2425 lbs with driver. I actually have to add weight at this point. I'm hoping the cold box will be enough, but if not, I can put a spare tire in as ballast.

Cold box? What's that?

Didn't realize you still drive the car on the road (didn't think it would be legal due to the roll cage). How much more weight do you have to add to be class legal? Aren't you still adding more to the cage, so that should add some weight. Does the TRD kit you got have the rear sway bar? If not, that should add a few lbs. And good idea about balancing out the weight distribution by the spare tire.

I have no knowledge on track/auto-x racing, btw, so I have no clue what parts are legal and not legal in classes.

Coolshirt and FAST are the standards, but I don't actually run their products in my cars. For the Miata, I built the cold box from a large ice cooler and a bilge pump. I needed the capacity to run in 100° weather for 2.5 hours. The Yaris is built for sprint racing, so the cold box can be much smaller. Rather than buy one for racing, I got a cold therapy unit on ebay for about $50. There are lots of brands of choices out there. McMaster-Carr sells fittings if you want to build or modify.

I'm only 35 lbs under weight. Fuel and tire should do it.

I'm not running the rear ARB because it's not part of the kit.
