If there's a stretch that needs me to stretch to the red, I'll do it, but if it's not necessary to redline, I'll shift a little early.
My tires would get greasy before the engine would overheat. I'm not the fastest in my group, but definitely pass a few groups too.
Having said that, I've seem someone in a 335 go limp with 2-3 hot laps. I don't know if BMW put in lower temp cut off's for limp modes in the newer cars since our 335 is a 2007 model with an Auto/Sport.

I doubt anyone here is redlining a 335, it's counterproductive to do so. Power drops off considerably after 5500-5700 rpm.
