I tried some fans to cool mine, but ended up with the BeCool duals and should have just started there to begin with....

Good deal man
Will I need to order that other crap below it, or will the stock fan-mounting hardware be sufficient?

I have a BeCool radiator too, and at like $600, I was not about to shove anything through it. Just a thought...... I got the aluminum brackets....

Will I need to upgrade from a stock radiator in order for that listed kit to work???

I am running the stock dual fans on my car with a 160stat and the ECM programmed for that stat and it stays at around 160-180 all the time. It did go to 200 one hot afternoon while I was auto-x'ing but that is expected since I was at 5K rpms for most of the course.

^See I need to rid my car of that crappy mechanical fan. For more reasons than one, one being I can't use my dual-snorkel intake w/out the elec. fans

I don't understand spending so much on cooling. My car with a 180* stat, and a lower temp fan switch/lower temps in the bin and my car is rock solid at 180 once it warms up. In traffic, at stoplights, on the freeway, heavy abuse, everything.

I wish. With BeCool radiator, dual fans, Flowkooler water pump, 160 thermostat, and it still runs 190-200 down the expressway. In the winter it is fine, but when the temp is 92, the humidity heading above 50%, and the A/C cranked, it is pushing it to the limit. Lose the heat, humidity, or A/C, and it would be a different story....
