Auto foam any good?

[Gerald 5]

Thinking of doing the above for my E46ci and E39, any good?Had the whole evening yesterday searching and reading the old thread and found different views and the thread were back in 04-08.Anyone have done this recently? any comment?Should I, should I not

From what I read, if it is not done properly...it will trap moist, finally RUST!!

are you refering to the foam thingy where you inject it to your chasis and sub frame?

YEAP.....that's autofoam.

I had a fren who did for his Mazda6 and it actually make the car handles better thru corners etc. Areas where you can reinforce include the A, B and C pillars and the main structure that goes from engine to the back.
However, his workshop mention to him that BMWs has one of the better chassis in the market and the autofoam thingy will not help much to improve what is already a very sturdy frame to begin with. Also it is more important that the particular workshop that you go thru to get this job done has plenty of experience with a particular car model as it get complicated when you inject the foam and you do not want excess foam to appear in holes where they have forgotten to plug it. Sometimes it can get messy and traces of foam may ruin your car. If the workshop has done the foaming on your model before, they will know which hole to plug and which to remain. At least that can save headaches later on.

I have autofoamed my E30 some years back... it was the B-Pillar and the door sills... Handling is indeed better especially on long sweepers, can feel there is less chassis flex.. But make sure that the foam used is automotive grade which doesn't contract and won't absorb moisture...

Yes, Its definately good. You can feel obvious improvement after 5 days when the foam is fully cured. I did mine at KL Auto.
The original auto foam. This foam does not absorb water at all and will be installed by professional with vast experience.

i think most car manufacturers built their car (pillars etc) & do crash test. basically means how car will absorb & "fold" upon tremendous impact during accident.

While its true foaming will reduce noise, body roll & improve handling but it may also influence how car will react during impact since the pillars (for eg. are harden up) In summary, safety maybe risked?

While we may be careful driver but we cannot control how others drive. Of coz that's my personal observation & opinion on foaming.

happy holidays & safe driving to all

Auto foam helps in handling in my opinion. Now I can go into corners faster and flater. The CBU units have foam installed at certain places

As for crash crumpling, it's true that it will influence how the chassis crumple. Therefore, it was not recommended to foam the front main thrust beams and also the rear...
As for the sides, frankly speaking, if a car gets T-bone, the foam might actually help. As the sides should not crumple as much as the front and rear... If the sides crumpled, can say bye bye to the passengers in the car aledi...

......even on the e34's and that is like donkey ages ago...they are already injected with foam....I saw this on half cuts.

hence most cars nowadays have side airbags and passenger airbag. I do tend to think on impact a certain level of force will trigger/activate the airbags. What the manufacturers have done is base on test & how their safety is deployed.

Additional further autofoam "may or may not" trigger safety on impact. while car may still be in good shape, it doesn't mean passengers inside are protected as most accidents we're caught offguard & we cannot control how we react/sway inside car. the deployment of airbags upon impact may help to save lives or reduce injury to its passengers.

Nevertheless, i did not surf around to look for studies or report though to link or disassociate autofoam. Just my own evaluation

Thanks guys for your your valuable input, I have decided to put in on hold till later. Thanks again

Of cos I was speaking about my 20 year old car which, of cos, did not come with all these mind boggling 3 letters car tech jargons.... hehe.. It was built to last till it rot and return to the ground.. New cars are made to last 10 years? If the carmakers keep making cars to last 3-4 decades, they will be lining up to file Chapter 11....

Anyway, professional installers may not even want to do cars with side impact airbags due to possible complications....
They would have no issues with lesser cars without having to worry messing up the electronics...

bro XXX, whereabouts the foams did you saw on those half cuts?...A, B or C pillar?...main frame from front to back?
