I was running through the canyons today with the sports bikes. It was only about 58-60F up there. I have an early steptronic with no oil cooler. Somehow I think even with an oil cooler, the temps would get pretty hot. It is nothing like the M3, which doesn't run this hot in 106F track temps! Funny thing though...I think I can run through the canyons faster in the sedan due to its greater torque. I ran a few bikes, none of them could leave me, and I was even running conservatively due to the glare I was getting from the sunlight hitting the dirt on my windshield. The 335i has no problems on the drag strip, but running hard on a road course is a whole different story.
Here a clip of one of the runs:
