Slow down is better ... you won't get the "bumping" effect on your car and your butt too.

wow, look at our scientis at work, come up with formula faster than einstien n it's good...

H = (T X S ) / 100 where

H is Hurt
T is Time to pass
S is Size of impact

The above is quite similar to the Impuse formula ...

I = Ft

where I the impulse
F is the Force and
t is the time

i just keep at normal speed 80-90km.......for toyota innova...(this includes speed bumps.) too high cant really feel bumpy too.....

on the volvo? on those potholes. really dont have any feeling..jsut go over like normal around 50-60kmp....probably due to the 19" or that i have not run over a really deep/big pot holes...muahaha

is bcos innova and volvo having different suspension system loh...

wow....80-90km/h over speed bumps????? your car will be "jumping" liao....you sure or not????

I am actually driving Myvi... Yet, i think my car stock suspenssion is not so good... Always vibrate like hell when passing the road especially uneven road.

The rear window is shaking like hell.... So, i wonder to speed or not to speed when cross the uneven road.

the conclusion is, slow down and change a better suspension.. haha
