Altima Coupe Chassis Braces Poll

[08altima35]

What do you guys think?

[08altima35]

also, these are in the making and hopefully will be availible sometime in the very near future.

dont these add like another 100lbs or so?it does make the Chassis very rigid but i wouldnt do it

[adidas2go]

I think its wayyyy overkill. I could see this on a convertible or a car with little pillar support, but the a/c has a sturdy cabin that flows well with the unibody.

You're talking about an underframe H-brace type of thing, correct? Or is it more of like a strut tower bar...without the strut towers?

[adidas2go]

how exactly do you have strut tower bars without the strut tower

Yes the "H brace thing" is what he is talking about

[ESP]

how exactly do you have strut tower bars without the strut tower

In the Toyota Echo hatchbacks there was a bar available that attached to the front of the rear-seat brackets (had to remove the back seats for it). The thing looked pretty much identical to a strut tower bar...

[adidas2go]

Strut tower bars are strut tower bars because they connect the struts together, with a bar, that towers over.

The object you describe sounds like a rear strut tower bar. Connects the rear strut together. Anything else is just a support bar.

...not a rear strut tower bar. They had those too, but what I described is what I meant; it attached to the rear seat brackets to (supposedly) help stabilize the midsection of the car. I saw a guy on cardomain who had both front and rear strut tower bars, this mid-section support bar, and both a front and rear underframe brace...'twas crazy stuff!

Nice description of what a strut tower bar is BTW, hahaha

[D-Roll]

He must be talking about this.......



I had it on my 02 Nissan SpecV and it helped stiffen the chasis especially good for autocrossing.

[adidas2go]

lol yea sorry, some people on here don't even know what fuel pumps do

Mid section stabilizer huh? That's some serious chassis flex if you need those

Its a supportive bar designed to attach the 2 main sides of your chassis together. To make everything stronger and less flexible. Typically on convertibles and long cars, to give support to the frame in a area where it could flex.

Its like the imagine above. That H section would connect in the middle of your chassis to stiffen it up.

We have a new installation article/overview of chassis bracing on the NICO homepage. Granted, it's a G35....

[ESP]

haha! No worries!Yeah, the Echo was a pretty floppy car until I stiffened it up. Neat thing is that after only about $600 in suspension mods it could take corners faster than porsches at the AutoX...best handling car I've ever driven (gutless as all hell though!)

I've heard that it's possible to over-stiffen a car though...is this true? My sources for that info were purely speculative though with no actual first-hand accounts.

Either way, I'd probably be down for a brace!

[adidas2go]

You can really only over stiffen your chassis, to this point, where its uncomfortable to drive. The stiffer the chassis/suspension, the more you feel the road. Stiffening, to a degree, will give you the ride quality of a motorcycle, but the handling of a Lambo, if you can keep your wheels from slipping. I would imagine you could stiffen it to the point of cracking though, If it was far to rigid, and nothing was able to flex with the road. Doubt it could happen with the minor amount of suspension mods that are out for our cars as of now

[Scandinavian Flick]

i personally think that it would be possible to over stiffen a car, i was thinking about it and if you over stiffen a car, the car would no longer have any at all flex to absorb the impacts of the road, i know there is a suspension that it supposed to take care of that, but the suspension is attached to the cars body and is constantly putting incredible pressures on it you would think eventually this would lead to cracking and the metal getting bent where the cars control arms and the suspensions components and where the suspensions mounting points are. just a thought, might not be true

[Scandinavian Flick]

a2g responded right when i was typing. same idea

[08altima35]

19 votes and the majority don't know what they are?????

i didn't expect that coming when i added it to the vote. Am I at the right place? This is Nico right?

[windhaven]

My 2-cents. This chasis is already stiff enough. As an example, I took a nail about 10 days ago, TPMS showed up the issue. So, I pulled over and looked for the bad tire ..... net, net, I couldn't find thebad tire by eye, had to take a pressure check.

Between this and the multiple times i've lifted the car at home and after lifting the front or back, when I lift the oposite end the whole end goes up with limited flex .... sort of tells me we don't need anymore....

1. The nail in the tire scenario has absolutely nothing to do with the chassis brace.

2. You would NEVER notice chassis flex of the car just by lifting one side and looking at the chassis to see if it has misshapen

[audtatious]

That is true. You would have to be in a scenario where one tire is completely off the ground and at the end of its suspension travel to see any flex.

Maybe I wasn't clear, my test is a 3-point scenario full lift of the car.... chasis flex can be seen in a 3-point scenario ... that's what i'm talking about (And, my un-scientific method involved the car completely off-the-ground, fyi). Some cars have more, some have less, and it can be measured. But, to be clear, the flex i'm talking about is vertical flex which is one of 3 flex dynamics.

It takes much more investigation to notice flex comprehensively. Short of a battery of tests using big equipment, the only way to decide is by how you feel .... sort of like a butt-in-seat dyno... and then there's the need to have a control population, etc. etc. etc.

As for the tire situation, if a car has a lot of flex, your tire, regardless of size and profile (Except when on Run-Flats) will demonstrate the flat (Compacting) ... some more some less. Cars with relatively lesser flex will show less. I was just trying to impart the fact that in my situation (Flat) that I could not visually identify the tire at issue (hence the potential for a perspective on flex).

All this said, very unscientific .....

I honestly dont think the coupes need the brace. With the suspension upgrades I have, it handles great in and out of cones along with awesome cornering.

[adidas2go]

Ah yes, the 3 point lift can be used to see the flex. I thought you were referring to a 2 point method
