The way out is through

What car? I thought there were a couple of versions of the STi that came with a steering cooler from the factory. Those coolers were on the high-pressure lines that ran behind the radiator, IIRC. They were basically just finned lines, not actual heat exchangers though.

An aftermarket cooler would have to go on the low-pressure side of the lines on the return to the reservoir. I'm not aware of any Subaru specific kits, but I wouldn't be terribly surprised if there was something out there. Certainly, running wide tires at the race track is taxing on the pump and fluid temps. I know my Miata used to blow power steering fluid all over the place at the track so often that I just gave up and removed the power steering entirely after replacing nearly everything in the system to no avail.
