I posted this question in the track section but that doesn't get much traffic, so I figured I'd post here to see if anyone has any input:

I'm doing a 335i brake retrofit for my 330i mainly because it was cheap and easy and gives me MUCH more track pad options. Anyways I was entertaining going with an aluminum hat rotor for the fact the aluminum doesn't rust and offers some rotating weight reduction (the 335i rotors are LARGE). Theoretically it would have less thermal capacity vs. a standard steel rotor set and I thought that on the track this may actually be a detriment even though the lighter rotating mass would help (JUST a little). Am I over thinking this? Price not withstanding would you still choose a solid steel rotor for tracking vs the two piece aluminum hat rotor?

Thoughts?

You're overthinking it! There are no advantages to one piece steel rotors other than cost

On a side note, how did the DuraGo rotors work out?

The steel rotor was completely uncoated which bothered me especially being in the salt belt. Spend the time taping it off and hitting with some high temp paint to prevent from rusting up completely, lasted about one winter now the steel rotor is a rusted mess. Aside from that everything else was good!
