The centerlock only adds a few LBS to the total un sprung weight.

The Moment of Inertia is the main concern in wheel weight. The Moment of inertia is what effects the acceleration and braking. The Moment of Inertia is not affected by weight in the center of the wheel. Weight around the outer perimeter of the wheel affects the Moment of inertia.

Imagine swinging a rock on a string in a circle and trying to stop it when you stop spinning it. the lighter the rock, the quicker it will start swinging and the faster it will stop. This is where options like Titanium hardware (around the perimeter of the wheel) are very important.

Yes overall wheel weight is important, but losing 1 LB of hardware weight on the outer ring of the wheel is a much bigger benefit then gaining few in the center of the wheel is a deficit.

Looks killer.
what happens to brake caliper clearance etc when you have a near flat wheel?
like say a 18x10 with 8 inch backspacing, can it be done?
18x11 with 7.25 bs, and clearance for monoblock calipers?

These go mostly on Porsche and other high end cars so brake clearance is enough to clear Brembo. We can clear ZO6 brakes which I think stick out more then Baer mono blocks, would need a template though

ok, sounds good. i know some wheel companies loose caliper clearance when thinning the mounting pad down, which i assume is what they do to make up for the thickness of the adapter.
cool part.

Frank, you are talking to an engineer, I know all about MOI. HAHA. And I totally agree with what you are saying. I was just wondering if this is one of those cool things, but doesnt add much performance. If it adds weight with no other gain.....

It is really freaking cool. And I have a perfect project these should go on.

Very cool...now we just need a 5-spoke in the competition series...:_paranoid :D
