This was all they sent me, and I'm hoping somebody can read and understand it and give us some insight.

Driving Impressions:

For YankeeLand roads Carl's setup is right at the edge (or perhaps just over the edge) of too stiff. For Southern roads it's probably nicely as-stiff-as-you-can-stand. For the Blue Ridge Parkway it's probably gonna feel like sex on wheels. It's not harsh and not obviously too stiff. The car's very, very planted. Feedback is good.

I found that parts of my test loop that I thought were smooth were actually quite undulating with the stiffer setup. For one of my off-the-highway exit loops that's otherwise pretty smooth I found that the suspension seemed a bit too stiff. Maybe, maybe not; I'd have had to go to Ludicrous Speed to see if it was stiff enough to skip. Also, it might be tiring on the highway for long distances. Carl "Iron Butt" L., will let us know at SITM.

Crap - the first dyno sheet scan sucks. Hold on to your arm chairs. I'll fix it presently.

EDIT: Fixed above. Had to go over it with a pen (never mind the splotch marks please.)

I like it a lot. Like being bolted down to the pavement.
After riding in 2 different GT3's, that was the ride I wanted. But I also know it's a street car and can't be ridiculous. The next thing would be PSS9's for a 928, but I don't know how often I would want to adjust it. I just want a good setting and then get used to how the car behaves and find the limits. At the speed limit...

So it's jiggly on less than Autobahn smooth roads.
Is it nervous on lumpy curvy roads?


Didn't Carl use to motocross?
So anything that doesn't shove his gonads past his throat is too soft of a suspension setting.

What was the PSI of the tires on the 18" wheels?
Makes a difference if you're riding low at 28 or hardcore at 35 psi plus.

Jigglier than stock would be accurate. It isn't super jiggly.

On the highway it is not at all nervous.
There are no lumpy curvy roads in my vicinity on which to test. The car is so planted that you'd have to be going pretty fast before lumps would unsettle it.

Yep.

Pretty much I think. (Actually not.)

Whatever Carl had them set to. I figure it's in the 34-35 range and that's correct for the tire.
