KB, it will be at least 85 Meganewtons per cubic quantum which is very stiff indeed...a very clever professor of automotive science in eastern europe
said so....
There see, no need to go to the attack forum now...

Is it still 85MN/q³ with the optional "flux capacitor"? I'm sure the blurb mentions time travel somewhere, and on the face of it,
the car should manage 88 mph without rattling your fillings out. Maybe.
To take a quote completely out of context: "... curved-tube horror..." - Forbes Aird, referring to a motorcycle frame.
Whilst I'm skipping from random thought to random thought... Aston Martin purchased two Ultimas for drivetrain development of the new V8
Vantage. I haven't found them yet, I think someone's hidden them. I know one of the filler caps made it's way onto a Vantage
prototype...

P.S. Yes, in case you were wondering, I work for Aston Martin.

That's without the flux capacitor...it would higher otherwise....duh..
Sounds like a quote from "Race car chassis, design and constrution"...?
Good book.

Hello Alan,
Yes indeed it is a quote from that book.
I just figured that (if GTM are to be believed) our Libra has a torsional stiffness of 14000 NM/°, or 10300 lbft/°. And our is a V6, so it gets a
couple of extra layers of fibreglass around the rear bulkhead where all the rear suspension is hung. Funky.

Back to the McLaren, I used it as an example of what a super-car needs for front suspension travel. This while I was trying to explain to the Attack
boneheads that you really do *need* it.
It works out to 4.9" to be equivalent. Thread here:
http://www.attackforums.com/showthread.php?s=&threadid=1145
Seven hours later, this pops up:
http://www.attackforums.com/showthread.php?s=&threadid=1182&highlight=suspension
... that it doesn't have 1.6", but 4.9" of travel.....
Damn, am I good or what. They could have hired me, "A 'well-known' designer who has a degree and works for a big company."
Seriously, I wonder if that was posted to shut me up. I still wonder what the travel *really* is.

I think my friend put it best about the attack.
"Ya it looks fast just sitting there but when a bone stock 350Z pulls up beside you, they will beat you without trying."
I would be scared about the lack of bracing in the cockpit. It looks like it could twist there. Ohh and whats up with using Audi stuff up front and
Accord stuff in the back? Now you have to my 2 diffrent sets of rims. 
Best thing to do for a build....
Ditch the wife!

In the Attack's defense (really) I think it'll win that race due to a higher power/weight ratio. At around 2100lbs (maybe) loaded weight,
and a stock Honda H22A1, that's roughly 10lbs/hp. The 350Z is around what, 3500lbs and 270hp?
No, I look forward to the day I pull up behind an Attack in *my* Mini. With a >400lb weight advantage, that could be embarassing to someone... me
if they have a turbo...
Of course I'm not holding my breath to see an Attack here in California. Since the boneheads refuse to listen about emissions testing, claiming
I'm making it up, they'll be in for a surprise, starting with their factory-supplied gas tank failing inspection since it's not
DOT-approved.
Regarding the Audi TT doner parts up front, yeah there's another surprise waiting for them there. Sure the Honda Accord donar car will be
reasonably priced because of its age, not so with the TT. It could be hard finding one in the wrecking yards this soon, meaning those pieces could be
$$$$.

BTW Spottty, you shouldn't envy anyone. Yeah so you can't start 'til summer, but since it's going to take years, it
doesn't really matter.
Oh, and while you can't start on it until then, you should be reading design books *now* so you know *how* you're going to build your
dream-car.
