Was at Bangsar the other evening. Could not see the road too well then
and by the time I came to a road hump, it was too soon and too fast for
braking. I suppose I hit the brakes too hard and the car dipped on the
stock suspension and hit real hard on the other side of the hump. Chipped
off a few bits of the oil sump fins - hope no other linked damages.

Perhaps too lessen the blow, it would be better to drive over the hump
without hard braking?

When one brakes hard,there is weight tranfer to the front.This loads the
front suspension and compresses it thus making it much easier to hit the
oil sump.
What one can do is
1. Don't go to Bangsar,
2. Change to stiffer springs and shocks,
3.Don't drive too fast and brake sooner rather than later.

What i find best in such a sitiuation is to brake hard and as i go over
the crest of the hump, release the brakes. This unloads the front and
most times avoid grounding the sump.

Hope this helps.

Cheers,
Doc

My ride is lowered on stiff springs so it doesn't dive as much. In my
experience, the best would be to jam the brakes as hard as you can (as long
as there's no car behind you) and release before cresting the hump. The
engine is in front and the bulk of the car's weight would be on the front
springs so going down the hump hard will be worse than going up the hump hard.

I would keep an eye out for oil spots on your driveway. You could have
cracked your oil sump by hitting it hard. Sometimes the leakage is not
immidiately apparent.

Good advise, Doc.

I use the same principal to go over humps, you'd be surprised how fast u
can take a hump this way!

For some smooth, wide and tall hump, u can go over it at 2X ~ 3X the normal
approach speed of 5-10kmh, without touching ground, with this weight
transfer technique. i.e. Step on the gas right when your front wheels are
at the top of bump, the car will accelerate going down the other side. The
weight transfer will keep the front up when the it is about to dip. If your
car suspension is stock standard, the shocks will compress enough but u
won't touch the ground. Timing is everything!

Soon u'll be yearning for more. I've done some pretty big humps with stock
std suspension at > 30-35kmh with no touch down using the above technique
and leave those modded low slung Skylines GTRs for dead, not to mention
Wiralutions, lowered Beemers, etc, hehehe...

In Sunway, there used to be some nicely shaped humps in front of Menara
Sunway where a std 156 can just glide over at the magical speed of 50-60kmh
without much jolting(can even fly past it much faster but u'll be killing
your suspension and knock your head on the roof) when other cars had to
crawl over it at 5-10kmh. NICE!!! Always made other driver's jaw drop wide
open when I did that!

Too bad those humps had been moved and reshaped, maybe they find these were
not effective to slow certain cars down huh? hahaha!

Don't try this at home, kids! And buy plenty of insurance for your oil
sump, kekeke!

suee,

do check out your power steering hoses as well, they are on the right
hand side of the engine. Just after RAISING my ride height, I hit a hump
that same night and kena the hose, which led to oil leak and then the
power steering pump went kaput! BTW, do change your stock suspension and
you will see a whole world of difference.
