car skid

[seviates]

Hey guys,

recently, i found my car totally unreliable for cornering
just days ago, i took a simple sharp turn and the cat skid
spun and hit the divider (bumper cracked)
i can understand if i had gone really fast, it was 40-50kmh
on 2nd gear.
I noticed this on highways too.
whenever there is a corner and slight uneven road,
the car is like trying to throw me off and i feel like
the back half of the car is not really holding the ground
i have changed drive shaft,steering rack, suspension mountings, steering bush

one thing i noticed i noticed is when turn the steering full either left or right
and then let go,the steering does not come back to correct position, its like it
something not balanced
using a putra and need you guys advise. I dont feel safe driving that fella right now

 

[myakac]

how about the tires? you replace all with new tires?

What about your absorbers?
Conked absorbers can cause skidding...
Also other items in your suspension system is in bad shape, loose etc...

i changed my tires all 4 of them within the last 6months.
i hardly drive too.
but considering that the ride is already 16yrs old, it could be the case.
just wanted to know if absorbers and spring could be the primary cause
of my problem

i'm thinking its a combo of that plus the steering thingy

 

[DanzEterna]

get some UR bars for the front & rear & adjust your camber too.

 

[ken yeang]

you drove on oil patch?? There could be some "human made" accident spots....

 

[LesleyAprotto]

Another cause could be your brake disc are too thin (worn out)

A very thinner than usual brake disc could cause your brake to self-jammed one sided...

If its too thin, i suggest you change the brake disc on both sides, front & back..

If you catch them, give them to the dogs first??

What tyres are u using? best not use silverstone or sime tyres

UR bars as suggested by Danz, I guess that would help.

There are only a few things that I can think of that causes that sort of skid :

1. Crappy tyres like Bridgestone MY01 tyres. I experienced the same thing as you at 20km/h.
2. You have overly aggressive or incorrectly set toe and camber settings. Usually apparent when driving straight and the car is fidgety.
3. Remove whatever bars you have especially the rear upper room bar. That one causes extremely oversteer-y issues.
4. If your steering isn't turning back, you need a new one. My steering rack died after issue #1.
5. Bent absorbers and/or springs. Dead absorbers and springs will just make your ride dead awful.
6. Dead bushes that change the geometry of your wheels.
7. Overly aggressive brakes that you stomped on mid corner. You shouldn't need to brake in a corner at those speeds.

Tried hard braking once cuz hesitated when reach corner at certain speed
Lucky got ABS if not sure skidded

Threshold braking and late braking is different than braking in the corner. It's easier to control an oversteer than an understeer!

 

[ken yeang]

the whole skidding can be traced from many aspect. From the thread starter, the speed indicated was about 40-50km/hr. However he didnt mention about how tight the corner was.

if taking tight corners, even at 40-50km/hr speed, I wont be surprised if the car can "buang", under the right circumstances...

 

[EvolutionZ]

for putra, u need to check the history of yr car. send to any mudguard panel beater and seek their help to view the car to determine any major accident before this...and send to a good mech to diagnose if there are any wear & tear parts need to change.
maybe after that u know where to tackle yr skidding problem

 

[ken yeang]

yeah, possibly the chassis sudah not alligned, or "crabbing" liow...

 

[EvolutionZ]

many possibilities, since many of our members have suggested some counter measures, do check on the chassis as well...on the suspension, cross members etc

From what I read, most stock cars especially sedan are designed to understeer rather than oversteer right? I mean from the factory set up?

They said it is because it is easier for a driver to control the car be it experienced or inexperienced
drivers.

There was once I whack a corner by hitting the brakes hard, my car skidded...well that is one wet road though and on Silverstone tyres...

 

[kazukimy]

huh...understeer much harder to control compare to oversteer,
well it was because almost all the normal sedan were FF, tats why tend to understeer under the extreme stress on the front tyres

 

[Supra_Fanatics]

Read it somewhere can't remember, it says it is easier to counter steer a car that understeered than designing a car to oversteer like last time...

(Kazukimy, ur car FR ma...surely oversteer easier for u to control...can drift LOL!)

 

[kazukimy]

erm, because of the momentum shift to the front side of the car (usually 60-40 in most car due to the weight of the engine) where the amount of stress on both front tyres were quite immense, hence losing traction and unable to control the 'understeer' angle no matter where u had change the steering due to the force/momentum that still forcing the car to move forward. whereas oversteer where ur rear slip whereas ur front still have somewhat grip to control where the 'head' of the car was heading, hence in my opinion, oversteer is easier to control rather than understeer, since nowadays most car have abs,ebd and vsc...understeer seldom happened unless u went over treshold limit or off the vsc..wakaka...

So with VSC on, the possibility of Oversteer is more likely? Never off TRC before...
