With the inner surface of the synchro being carbon, it has a better surface contact than the standard bronze. The carbon also lasts longer than bronze, meaning they dont wear as quickly and promote smoother shifting at high rpm

Interesting.
Are there any disadvantages? For example, does it also shift smoother if not equal to OEM in lower rpm range? Would it require uprated MTF for this work well?
I have been using Synchrotech Carbon synchro's for the last 6 months (have rebuilt approx 8 boxes in this time) and have not had a single issue with one of them. They have better engagement angles than OEM as well which means its easier for the slider to move over them.
I use Penrite oil's in my shop and for a car that gets driven like a baby, I use Penrite Trans Gear 75W80 (semi synthetic / direct replacement for Honda MTF) otherwise I use Penrite Pro Gear 75W85 (full synthetic) for cars that get driven fairly hard. Both oils do not cause any harm to the synchros
