Buttoned everything up, reinstalled the bumper and brought the car home with everything done except the splitter install. Feels good to have fresh engine and gear oil along with fresh coolant in a big ass radiator and low temp thermostat. Also washed and reoiled the K&N air filter. Running smoother than ever.
I installed the support rod brackets to the crash beam and installed the downforce vanes to the bottom of the splitter.
The radiator and low temp thermostat are definitely doing their jobs. I haven't hooked up my OBD2 adapter to Torque yet but the car previously always ran at the dead center of the coolant temp gauge and now it's running barely above the first notch fully warmed up. This should make a big difference on track in the middle of summer.
