Big difference I think between those tires and the Contisportcontact 5 RFT. I also tracked my Z4 with the Bridgestone 050A I RFT and that was better
As for the additional heat exchanger, it is called "auxiliary radiator" by real OEM and the lines looked like coolant and not oil lines. You'd know better since you have that car. Just sourcing where I got the info. 335 is my wife's commuter so I didn't care too much about the cooling when I got it. Just wanted to track it once before ordering the M3 to make myself feel extra cool about the decision.

As for the fan, it is 850W for m sport and 600W for non m sport. Similar situation with the 1M and E9X 335is having that fan and additional heat exchanger setup versus the Z435i/is and F3X/E9X 335 having just the oil cooler and 600W fan
