im usually drive 140kmh on highway.. can hear my radio clearly.. stock car..

I adi soundproof except for firewall, ceiling and rear door

For the floor soundproof, see how 'deep' they can extend inside the pedal area, it can reduce engine sound, but not much.

To reduce engine sound, you must do fender, mudguard and front door. Front door i did 3 layer +  sound proof door rubber, give me huge different in engine noise.

Now overall the engine sound @ 5k rpm = 4k rpm as before soundproof, for me quite satisfy without soundproof firewall.

As for tyre noise, is approximate 40-50%. When i done all above soundproof my damn tyre only @ 20k mialege, now i can clearly notice that the tyre is damn noisy, can hear noise during speedline.

Guys, I lost the small chip-liked thing inside the remote. How it looks like? 
And now the car cannot start. Have to use spare key.
Expensive or not if replace the chip? 

but my car already 3 years...i dn't think they will let me claim
so it's not absorber's problem or alignment prob??
cuz i just find out today only...might want to monitor it few more times see if it's really go down...

it only solves the alignment problem only??....lol
if alignment problem...thn easier...just do the rear alignment

torsion beam cannot adjust but i can make the rear alignment straight
since the senget one side cannot be fixed...mind as well fix the alignment only
and what's the "sign" that they absorber need change?...squeeking sound?

only thing for u to do is to add in washer if u insisting to make it more outward to make it even on rear left

i got washer for u to test till u like it then i'll make 1 custom spacer to fit ur car,otherwise u'll have vibration prob during high speed~
then try take out ur air-cond filter n clean it out~
