I get my info from Tremec the manufacturer. I recently pulled a 2010 GS trans with 10,000 miles out to replace the bronze synchros with carbon fiber. The only synchro that was carbon fiber was second. The rest were sintered bronze. It now has carbon fiber in 2nd, 3rd, and 4th. I checked with Tremec before posting this to see if the 2011's were the same and they told me they were unchanged from 2010. I'll check again with engineering after the holidays to make sure.

Can I ask what the reason for this change was, did the trans have issues?
I have an 09 coupe, would you say that this "upgrade" to the new 2010/2011 synchros is worth the time and money of removing/rebuilding the trans? There's nothing wrong with my trans, other the then known cold notchiness...
Thanks, Sonny

Absolutely no reason to upgrade. Your 2009 has the same style of synchros as the 2010 except they are all bronze. If it's shifting nicely I'd leave it alone. I changed mine because I needed to pull the tranny for other reasons and thought WTH. Mine doesn't shift any better with the Carbon fiber. Carbon fiber synchros were put in the 2nd gear position because 2nd usually takes a beating and is first to go in a consistently hard shifted tranny. The bronze synchros will give you long life if not abused.

I also confirmed with Tremec source that newer TR6060's have carbon (they are really compressed carbon) synchros ONLY in second gear. I was also informed that to change over to carbon 2nd gear synchros, you must replace the 2nd gear as well.
