"For the record, inboard coil-overs do not inherently reduce unsprung weight. They still have to move, and their inertia is part of the sprung weight. In fact, because the control (rocker) arm has to be heavier, the net unsprung weight will probably increase.

Formula cars have their springs and dampers inboard for aerodynamic reasons, and it makes it a bit easier to integrate driver-adjustable anti-sway bars."

Bob is quite correct.

The only possible reduction is that the damper itself is not part of the Unsprung weight.

The JBL rocker weighs about 4.7 lbs. with the outer rod end. I would think that most upper A-arms are in this same range or lighter.

One of reasons for the rocker system on the JBL is just as Bob stated. Packaging. This arraignment allowed for the anti-roll bar system and its adjusting bits.

The main reason however was motion ratio.

Cranky,

As I stated in my previous post, I really do not know enough about dampers to help you much.

It seems to me that you would be better served by other members of the forum, particularly in the "don't want to hear and don't understand the tech talk" bits.

(Also please note that you have spent your entire damper budget on my consulting fee at this point.)

Now, as to increasing your speed at the Glen.

The only thing that I can think of is to stop using the brakes so much. That is why the ARMCO is there.

As Ettore Bugatti once said "My cars are made to go, not to stop".

He was at the pinnacle of the sport you know.
