I'll go one step further and say that it is my
belief that an aluminum flywheel makes high rev shifts a bit safer because the likelihood of breaking the rear loose is lessened. Personally, I don't like breaking the tires loose on, say, the 2-3 shift at just under 70MPH. With the aluminum flywheel, it feels like the lesser amount of "stored energy" eases the shift somewhat. Now, of course, I could just be fooling myself.
