Do you mean the chassis or the suspension?
chassis, by adding all the strut bars sway bars, what not, and the hardening foam.
what is up with the poll? Can you just ask question without poll? Fact or not, can not be determine by poll. Just because something has majority follower does not mean it's right.
To answer your question, there will be a point where you get to diminishing return.

I'm with Andrie, enough of these polls.If you want to talk about something,then lets discuss it,yes or no is not sufficient for many of these technical matters,,like drifting!Afaik the more rigid or stiffer a chassis is the more effective it makes the suspension,therefore this would be more important as the suspension becomes more performance oriented.
geez, if you guys hate polls so much or this tread then why not just ignore it and not post in it

Good idea. I'll stop responding to your questions.

With that attitude, you'll be lucky if anyone will take you and your threads seriously anymore.
holy crap... 3 posts within a minute of each other. 
we need to get a life outside of smoking the go-fast-crack-pipe... Andrie, see you in 20 minutes at the pizza place.

Or we could hijack (again!) this thread for some discussion about the orthographic qualities of the thread starter - like: Yo, yo, my chassi's to stiffle - so take my stiff riffle (or was it rizzle?) :biggrin:Andrie Hartanto said:
Sorry, I did not know that correct spelling and grammar was so crucial in the NSX community. As for my attitude, I was just answering Andrie's question about this poll. The point that I was trying to make, is that If you have nothing better to say, then why not say nothing at all? If you think it is a stupid question than good for you. All I wanted to do was create a simple discussion, I did not expect that it would offend anyone. And BTW, where do you see any rizzles, izzles or yo?

My point, is poll is not needed. A poll is a popularity contest, it has no bearing if the winner of the poll is actually correct or not! I don't think it is a stupid questions, what I meant is asking a question in the poll format is stupid. Unless of course you want to see which one is more popular with no interest knowing which one is correct.

Man, this guy's got a stiff rifle! :biggrin:
ok ok ... back to the topic at hand:
A chassis can never be 'too stiff'. A chassis is not meant to flexible. Predictable handling depends on chassis stiffness so that in a corner any roll is due entirely to the suspension. I'm not an expert so I'll share my understanding so some of Prime guru's can correct me later. A stiff chassis can improve handling and allow better tuning changes to be made (ie. to the suspension).
I imagine there is a point where you can try strengthening a chassis unnecessarily: too many crossbars, etc. could weaken the main frame. It also increases weight, and if you're not careful with your placement of bars you could start to effect the ideal 50/50 weight distribution on both front wheels and both rear wheels. This would have a very negative impact on handling.
Could NSXTASY, D'Ecosse, other knowlegable people please correct me on this? hehehe.... i sound like a noob huh?

From the AutoZine Technical School site, take a look at the Handling: Chassis Rigidity section. This site covers a wide range of automotive concepts on the site, explained at a high-level in very easy to understand terms.
Ok, now that we’ve got the serious stuff out of the way... back to the fun.

No, the chassis can not be too stiff since it is designed to be static. However, as mentioned above, there are diminishing returns due to factors such as weight and costs.

if i jack up the X on a not-entirely-level floor, it will rock on the two highest jackstands (hey, my car ROCKS anyway!). i think that's a pretty good demonstration of the stiffness of our little hotrods, although you want to be careful not to kick out the jackstand that doesn't have any weight on it!
Formula One cars generally have stiffness rates in the range of 15 000 ft-lb/degree. not bad for a tub that weighs 90 pounds.

I think all cars are built as stiff as possible, some limitations being:
Weight(adding more material makes things stiff, heavy things take more energy to effect their direction of motion)
Size constraint(has to fit on the road, smaller is more aerodynamic)
Passenger compartments(cars would be stiffer if door did not open and there were no windows)
Cost(FEA computer time, autoclaved low-void carbon fibre, titanuim fasteners, etc.).
As Chris said, the idea is the chassis is static in theory. The closer one can get to 'perfectly stiff', or static chassis the better the suspension will be able to distribute load in the manor it was design. I think the art is designing so the slight flex which happens in any real system has no negative effects on how the chassis works.
All the races I have seen were won by the car that got around the track in the shortest time, I don't remeber how the stiff cars did? :wink:
