Something to do with the drive shafts rubber absorber thing which is missing. Some persona came with it but many not thus result a bit vibration when u accelerate > 100km/h or 2,800 rpm. Heard Proton Edar will add this into your drive shafts..other appointed workshop or perhaps Eon dont. This rubber thing is available at  Gen 2 or most car but not on Persona. Go check with Proton Edar SC.. I donno what it call on the absorber thing that was included in the drive sfats to minimise vibration especially to the pedal.

Havent rectify mine but will do that the next service. Is your SC an appointed one...tell him about the absorber rubberish thing he will just go...???????????? clueless.

There are 2 reason will coz this vibration, I feel that too when reach that rpm....

1. I do the balancing and alignment and not so obvious already.

2. Most of the Persona don't have the "DRIVE SHAFT DAMPER" you can have a look at the picture the red circle. Try to ask SC to add this things, The inside the rubber things got small stone which is absorb vibration.

Mine none...but what do you mean by boot cover? Beleive it is cloesly call dampener for to dampen the vibration.

Notice most of persona missing this. How come you got it at yours?? Sure or not?? Probably you identify the wrong one. Go check it out again.

anybody got heard a sound "Tok" when went over a bump or unevent road?

I am not sure where is the sound come from, but feel like under the car, just don't know which part...

Hi,
When did you go for 1st service ? Which proton edar service centre?
The SA told me to bring the car to Shin Hin Tayar Ampang. Actually, I want to visit  proton edar Cheras or Puchong.
And there is World Car Care Seri Petaling near my office. Is it recommended?
Please advice.

Thanks.

from AFC meter = 8.5L/100Km
but actually, when fuel indicator showed empty then fill-up RM50, can only run upto 125Km till the indicator blinking again.
Any one knows how the AFC meter works? - it seems cannot be trusted.
