Here's a picture of a rocker that we did for a 356.

And BTW. Our 356's rev 8000.

How come you dont use aluminum or titanium rockers...I mean make them..


Fatigue strength, cost, workability, longevity.

The benifits of lightening cast rockers, are small, but when trying to find every drop of performance everty little thing adds up..

The Moment of Inertia of a rocker arm that only moves a few tenths of an inch is small to begin with,

It's really R&D time to make them. None of the above. If there was truly a will to make them, then we would.


And....

directional carbon fiber reinforced titanium rod.

Think about that.
