I think...Oil coolers bennifit the following cars:1.those with OIL COOLED TURBO UNITS. because, duh, the oil is getting heated far more than usuall, thusly may have problems with degradation and temperature.2. THose running cars under constant high RPMS for long periods of time, such as 2 hour or longer endurance racing, or races in very hot climates.
otherwise, its just a little add on to make you feel safer. I drove my 300ZX at road atlanta for 2 hours straight with a oil temp meter, and it didnt change much after initial warm up. I think of more importance for reliability is a good coolant system for overall engine temp(this goes up when road racing far more than oil temp), and if you rebuild the engine, getting a better oil delivery system(upgraded pump, engine bearings with oil notches, dry sump system if possible).
transmission coolers are nice, but really only of great bennifit under the same circumstances, and for automatics.
