I have an upgraded Alradco aluminum radiator and a 14" x 11" oil cooler. With ambient temperature of 75 degrees, water temps easily hit 240 degrees. My power steering fluid got hot and had some spillage so I will be adding a cooler. If you run more than 30 min you should consider a differential cooler.
Suspension mods will be most important. Creative Steel is a great source for motor mounts, toe rods, control arm/subframe/ and other bushings, shifter, 8.8 differential. I did Addco sway bars with Ground Control end links, LG Motorsport coilovers revalved by Performance Shock, Bridgestone RE71R tires and track alignment settings.
This past weekend at Sonoma Raceway g-meter showed 1.25/1.28 g's.
