Brake boots melted, metal rings falling out. Bought some fresh calipers (for unrelated reasons) and put in a set of BCB vented pistons, high temp seals, and high temp dust boots purchased from @555engineering
This may be the most important mod I've done to my car. A seat lowering bracket made by @delta.x.motorsport , intended to lower the (quite good) factory seat down around 1.5 inches in the rearmost position. 1.5 inches doesn't seem like a lot but it made all the difference in the world. The seating position went from crossover to sports car. I finally fit with a helmet! I burned the classic Delta X titanium hardware gold.
Huge shout out to @555engineering for being the king of GR Corolla cooling. Installed the oil cooler with a carbon side vent, and soon a transfer case cooler.
