Hey guys, I'm more known in the sc forum but i have an Is300 with a built bottom end stock head, 6062 dualball bearing precision, ecu master black piggy back with stock computer because shimm'ed auto transmission for now

Basically I'm seeing the stock fans kick on at 220, and i want to lower that temp. I'd love to see them kick on at 200. Currently i'm just running the A/c to make them turn on but thats also robbing some power/ not required or good at high rpm pulls.

I know the temp switch in the bottom of the radiator controls there operation. is there a switch out there with a slightly lower closing resistance and triggering the fans temp?
