Severe Understeer

[Eazyy]

Hey guys quick question for ya'll.

Just traded my n/a S13 for an R32 Gtst a month or two back. Sweet ride dope deal on my end only downfall is its auto, gotta change dat shit! Pretty stock, wider wheels, fmic, blow off etc.

Anyway I have noticed I have really bad understeer when driving in the wet. I literally have to slow down to 20km/h to get around a roundabout without the front wheels locking up on me. Its realy wierd since the first thing that kicked out in the s13 was the rear haha. In the dry its fine.. Anyways just wondering if anyone may have an answer for me or something of use i could do.

Cheers guys

Hmmmm let me think.

Wet road.... front wheels don't turn....

Have you even looked at the tyres? What brand how much tread?

[Eazyy]

Yeah looked at the tyres and theyre not bad at all id say around 65-70%, however ive never heard of the brand before, slips my mind atm ill have to double check.

Take it to a professional. Even cheap tires shouldn't be that bad. That sounds way to dangerous.

I'd be slapping a decent set of new tyres on the front and getting a wheel alignment.

Tyres are an obvious start, but other suspension components like shocks should be inspected. Worn bouncy shock absorbers will negatively affect front grip.

Pump them up to 40 psi

car could be slightly bent, look out for uneven castor from the wheel alignment print out

[Reese69]

thats odd - try tyres and alignment for sure - last track day i had - my rear end went out, shifting from 4th to third- soon as the clutch came out bam so did the rear end -

hope you fix it - bugger if i would be driving it in the wet if its that bad

I used to own a 4WS Prelude daily and in the wet it couldn't follow a Vectra around a simple corner.

Damn Nankangs needed changing despite 70%

Yeah, cheap tyres, including a lot of the chinese stuff (ling long, nankang etc) are horrible even with tread.

OP check out what tyres you have, and what pressure they're running and post back.

I use to have some no brand chinese tyres on the old XR6's rear, 1 drop of rain and i could have walked faster around a roundabout without getting some serious drift angle happening, it was so bad that i stopped the family driving it till i changed them.

There would be no g force through the car sideways, you would swear it would have been impossible to get a car sliding at those slow speeds, yet going around at a stupidly slow speed yet the rear would just break out in a blink of a eye.....

Dont buy no name chines tyres, tyre shops are selling them everwhere, they are death traps.

Makes me wonder how many people have been booked under the hoon laws with them or wraped the car around a pole and been told by the police they were driving like idiots and charged.

[Hadouken]

I can see how that goes down with a cop who just pulled you over for sideways action.

"I swear sir its these new nangkangs, says the guy who bashed limiter at full lock"

Nah but seriously. shit tyres are shit

Even the khumo ku31 on my pulsar had zero wet traction with 50% tread

Cheers for the replies guys appreciate it. Checked the front tyres, a brand called kinforrest? Never heard of it so I'm assuming they're rubbish and I'll replace them as soon as possible. Approx 60 % worn with more wear on the inside. Will ask my mechanic friend to take a good look at it once new tyres and wheel balance and alignment has been done.

Kinforest are terrible.

i had bald rears on the XR6T and brand new (2000km old) kinforest on the front.

in the wet i could turn the wheel, step hard on the throttle and the rear still had more grip and the car would go straight.

i didn't even bother to wear them out, at 3000km old i left them at a Bob Jane, told them to do what they want with them, except resell them.

change tyres, under steer be gone!

[Eazyy]

^awesome man gives me decent hope haha changin them asap

[Hadouken]

lol, just change them already!

Sounds like you should check your control arms and bushings if there is uneven wear. No point prematurely wearing through new tyres before its fixed.

[Hadouken]

or wheels out of allignment. Or over/ under inflation. Or previous owner loved drifting Or so many things.

One thing at a time I say, new tyres, wheel alignment. Boom

[Eazyy]

appreciate the replies guys helps alot thanks!
