Just had this done on my 2010 Z (stock radiator, no oil cooler) and I love it. Temps outside now are about 90 degrees and driving down to Z1 resulted in oil temps around 220 on the highway and 230-235 quickly in stop and go.
Stop and go now is consistently 205-210, highway is 205-215 (lower fan speeds used when going faster) and the car cools down extremely fast at idle from those temps.
Props to UpRev and Z1 for making this possible!
