what is chassis/body strengthening?

[Izso]

Well what about chassis foaming ? Do those help besides NVH. I see alot of cars like to cover their bottom with those.

There are multiple types of brands out there so let's just talk about Autofoam. Then it hardens it becomes pretty strong therefore if it was pumped into the sills, hollow chassis "bones", pillars etc - it'll expand and stiffen the usually hollw metal beams or whatever. Technically it should stiffen the whole frame and reduce "echo" or dampen sound. So yeah, it should reduce NVH and stiffen the car overall. But there's a caveat too - even Autofoam has 2 or 3 types of foam. The "race spec" one is the one you'd want to go for if the car needs to be solid stiff. The 'weaker' foam is stiff still but less.

It's all about trial and error if you ask me. I've tried both the cheap brands and the premium Autofoam brand and seriously don't bother with the cheap one.

I'll check out autofoam

Theres another brand called acoustec by Ottimo car audio accessories near ss3. How is that one if any users using? From Ukraine. They told me they went through proper courses to learn professional installation. Got fb page tok

Their cny promotion package for sedan and hatchback
Full car RM3040
Road Noise Package RM1520
Door package RM760

Road Noise Package = Whole floor panel, firewall and wheel arch
Door Package = 4 doors

*shrugs*. Never used before.

I wonder if the roll would have been lessoned if it was a car rather than a high up SUV

nah. the impact point the vios hit is spot on. on a normal car it'll still roll.

 

[gunnerzz]

nah. the impact point the vios hit is spot on. on a normal car it'll still roll.

Maybe its time the VSC system is upgraded where it will try to avoid roll even when one corner is damaged after initial impact. Something like an advance moose test.

so far, vsc is designed and tested om its own right? meaning under controlled environment.

vsc programming always including rollover avoidance/control in taller vehicle in modern suv...


stilll adding stiffer anti-roll bar would help much as well because...its lessen body roll..equal to preventing roll when turning or swaying side to side... :smoke:

The controlled environment also at a controlled speed, not top speed.....

hard to say right? might just spin out?

Anyway chassis strengthening doesn't help much in terms of safety, as modern cars are designed with proper crumple zones and maintaining cabin integrity.

Also, old cars, although strengthened still suffer from fatigue over time. So it just depends how severe is the use and stress. I remember reading spot welded chassis, when crashed, won't be able to be repaired.

so what u mean is if I intend to use the car for the next 10 years, doing autofoaming is probably a waste of money and best to keep stock since wear and tear is bound to happen? bec I want to know that I will be spending some good earned money into something that actually provides the benefit i seek haha

What i know of is insurance wont cover if found there are autofoam or chasis changes on your car during claim. It is either a loss to you for your car

Not really. My wira has autofoam. Didnt affect claim when I got rear ended. Just that when they did repairs, the foam has to be dug out from the side sill.

 

[parakey]

After the penang bridge news
I think I need to do something like this d. Scary news

When you say chassis strengthening, which car from the accident did you mean? The CX5 or the Vios? What do you have in mind? Which of your cars do you plan to do it to?

nah no issues there, have enquired.

A Toyota Altis will outperform a Perodua Myvi no matter how you autofoam it. And a 5 series will outperform a 1 series no matter how you autofoam it. Cars keep improving. Better save money and buy a better car 10 years down the road.

Of course if you plan to drive the car until the wheels fall off, then you can autofoam it.

When you said outperform, I take it you mean from a safety viewpoint. On this, I agree with your views

Not only safety, but NVH as well.

 

[parakey]

Not only safety, but NVH as well.

For the given examples, I agree on NVH too but if handling is a consideration, I might digress

Well in my example, con9lan7firm Altis will outperform Myvi in handling no matter what you do (been there done that). Of course it depends on the cars being compared.

I have a myvi and a latio
Of course myvi gets priority.

But i am concerned on this insurance claim thing in case of accident and also of super stiff since I have stage 1 bars installed

Autofoam isnt that stiff. No need worry about it. It's more of a NVH aid rather than chassis stiffener.

I asked earlier but you might have missed my query. What did you hope to accomplish from stiffening with regards to the PG accident? If Vios, stiffening to have better handling to avoid losing control. Or with CX5 to better withstand getting smashed into?

I dont think chassis stiffening might have protected the CX5 much. For protection, do like Ixeo mention. You need a bigger sturdier vehicle
