Are you the Waja owner with full Ultra Racing side,rear anti roll ,front lower 4point and front strut bar ?
You did mention the UR's bar is not significant also. Maybe you need to foam the whole car?

bro i got 2 Honda city friend interested one coming to do with u soon.. i coming with him.. the other one waitin for review.. anyways..

Day 4 on foaming

PROS

Ride comfort has improved alot! my car now feels very solid and stable going over bumps and uneven roads or even pot holes. My car now feels planted on the road when travelling at highspeed. Tyre noise is 80% gone but now i can hear wind noise only damnnnn...ahhaha..

Braking- Tested 100kmph-0kmph emergency brake today. My car didnt sink forward as much like it used to last time.

Cornering and Overtaking- Now after 4 days of curing.. my car is very stable at cornering.. i also feel more confident and safe when overtaking cars at highspeed.

CONS:
AIYO NOW I TAKE CORNERING VERY FAST LA.. tyre botak faster.. HAHA

oh yeah..just wanna say..A MOD THAT EVERYONE SHOULD DO BECAUSE IT REALLY WORKS!

cheers

I see, maybe the car is so new that you are not used to it yet, if not mistaken, your ride is 4 months old right?

I think you are not used to the car condition since its brand new car, thus someone did mention that its best to drive your new car until you are very familiar with all the noise/wind noise before foaming it. Else, its like drinking water when you are not thirsty.

bro 5500km only? so new..    anyways.. i remember last time when i first gotten my car.. i was thinking omg this car DAMMM quiet.. (upgrade from myvi ma) haha so now at 20k mileage the tyres old d and DAMMM noisy.. kumho tyres very noise after 15k.. my salesman also told me once.. he said do soundproofing after 15k mileage as you will hear the diff when yr car gets older.. 

On the other hand, virtually all of our competitors actually utilize Construction foam, which is not only meant for a different application or environment, but for a totally different industry.

Thanks bro for helping out as i dont have a garmin gps. Wah, the name underground is nasty man. Should call it Underground Chassis Foam. LOL~
You foam already not to worry. Just marketing only. Eg. Would NASA space shuttles' foam/sound insulation be use in automotive is better grade compare to only automotive grade ?
Its all marketing. Please check out at technical section there regarding this. I think one member posted a very detailed information there.
Its all just marketing talks.
