Dry> Understeer, Wet> oversteer?

[Boyboy]

I face these "scenarios" as mentioned above.

 

When cornering on dry roads (whether fast or slow), tendency is almost always understeer, unless i clutch out when cornering. Usually i give my 'goo some accelerator to maintain traction.

 

When cornering on wet roads (fast), tendency is for the rear wheels to break free. kinda weird since my 'goo is a FWD. i was revving happily thru a corner when this happened. wanted to test if bangoo will still oversteer but that was wad happened.

 

is is possible to have *predictable* handling? on wet roads i will never be sure whether i will understeer or oversteer. Of course the lao cheows will ask me to slow down but i only do such cornering on wide junctions with no cars around (there are some in NTU ). Short of getting a new vehicle (which will be a van anyway! )

 

I'm thinking of lowering my 'goo for extra stability but i don't think it will affect the cornering. then again, i may be mistaken

hmmmm...some say it's the tyre but majority say it's the skill of the driver & how well the driver knows his ride....

 

but, i always make it a point to slow down regardless whether got vehicles on the next lane or behind me or not.... this practice has served me quite well cos 1 evening i was exiting from BKE toward KJE, i was on the inner lane with ample shoulder on my right. this car overtook my ride from road shoulder. luckily i was going slow otherwise the papers would hv reported a car flying & landing on BKE towards Woodlands...so the morale of my experience is expect the unexpected....

[Boyboy]

partly my tires, and i am still getting to know my ride. tt's why i push it around safer areas (and not the highway or at high speeds.. ok, i do speed but tt is in a straight line)

 

to kup corner at high speed is sth i dun dare due to high CG..

 

i guess tt is a good motto, to expect the unexpected. but i'm trying to find out how the van will react under diff conditions and handling, so tt i can reduce the unexpected

[Qpik]

i know where u r coming from...but, after driving around so many sharp bends especially my place.. cck.. i noticed the experience is different everytime... even on same road cos the conditions might be different

[Nhrisuzu]

go try heel-toe around a corner with ur 'goo.. u will be thrilled..

 

anyway, on a serious note.. don't push ur 'goo too hard on turns.. high CG is quite a hazard when cornering, roll too much will become a sleeping 'goo..

[Qpik]

sleeping goo or turtle goo???

 

even those with lowered ride are not spared

[Nhrisuzu]

don't think will turtle ba.. so far, the worst i seen before was a sleeping Cabstar..

 

this cabstar with a high alum. box was in front of me, chionging quite fast..then he like super confident, makan the corner.. in the end, never make it out in a piece.. flipped over, landed on its side.. driver came out scratching head..

[Qpik]

me saw 1 turtle last time...was on the way home...2 fellas overtook me, exiting towards bke (near the kranji turf club)

 

both rides was very low, jio-ing each other ...both cars i think was trying to outdo each other on corners suddenly one of the car just flipped...

 

i got shocked cos i heard a loud bang, nearing the corners saw 1 sleeping & 1 turtle...quickly exit by turf club exit ...

if slow also understeer , you are not slow enough. :)

 

u are breaking at the bend?

 

what is your ride?

having stiffer suspension does help the car stability when doing fast turns.

 

lowering means lower CG, it has to go with your suspension stiffness.

 

the more u understand your car's setup and behaviour , the more predictable it is to u.

You're still going too fast for the tyres. try getting something grippier or slow down.

Btw,take ur foot off the acclerator rather than clutch out as you want power to go to the wheels for control.

Thats coz of the live rear axel and the lighter rear than a regular car, and coz its more slippery in the went mated to your clutching in = lift off oversteer. Once again better tyres + go slower + decelerate rather than remove power from the wheels. I betcha that u were also braking as well when it happenned.

It should help but look at tyres first.

Its your tires. Wet weather tires should help. Or......LFB .

Not on wet roads. Water has no definite shape but still forms round or oval if u notice. So just imagine having ya wheels over a puddle of water that's round or oval.

 

So which side will ya rear wheel slide to?

While wet cornering, I avoid braking. I braked before the corner then accelerated in the corner. i wanted to avoid the lift off oversteer but apparently i was going too fast. so end up let go acceleratpr and countersteer.. quite fun.

 

tyres behind are 185/70 R13 with ample thread, but they are old. i know i need to change them

 

i wanna lower suspension not so tt i can go faster (i think the limiting factor is the tyres right?) but for additional stability..

Unlike other bros here, i will simply tell u that Every Vehicle is made for a different purpose.

 

If you have to consider so many factors ( CG, Tyres, Suspension, Height ) to make it more stable ( with such large adjustments to each factor ) when cornering, then the vehicle is simply not made to turn at that speed. I infer from you posts that you are driving a Van? There may be a good reason why Vans are not used in races.

 

You are like asking Mac to do Fried chicken as good as KFC. Its just simply against the way things go.

 

I dont recall any wide bends in NTU for you to play safely. I do frequent NTU sometimes. I hope you do not crash into me.

[Boyboy]

which side will it slide to? it will slide outwards.. i dun think it can slide any other way right?

[Boyboy]

well, i agree with u but then again, we have family cars going to pasir gudang. i doubt that they are made for tracking. i am not so ambitious..

 

there are.. at the junction coming in from jalan bahar. unless u r speeding n i can't see u in time, i doubt tt will happen

 

they do have truck racing u noe? I saw a video of this huge truck (without trailer of course) drifting.. I'm sure a van has lower CG. anyway, thanks for the advice

[Mirrorimage]

Yups. Tts why the family take the effort to go to Pasir Gudang.

 

Hmm..U are talking about the big cross junction in front of the Graduates Hall?

 

Both sides have humps...do you fly over the humps after you corner? or you slow down for them?

 

Yes...that junction is pretty safe...dont think u will hurt others unless others are speeding too.

[Boyboy]

Its your tires. Wet weather tires should help. Or......LFB .

 

wrt tyres, are there any decent tyres of 175 (or even 185mm) / 70, 75 or 80 profile for 13 inch rims? i dun intend to change to sports rims or even upsize my steel rims.
