R33 Oversteer

[Guest Robo's]

This is the first car i have had with severe oversteer. I want to reduce it!!

Its got Tein NR suspension, rides very firm, i feel this maybe the cause. Also 17*9 at the rears with 255/40/17 which mean it should hang on, but it doesnt, any good throttle will send the rear out, i might try reducing the back tyre pressures to reduce it.

Anyone elses opinion.

if that tein is adjustible, possible your rear settings are a tad too firm. it might have been set for drift where the tail will kick out easily. soften it a bit might help.

[red900ss]

Yep soften the rear suspension. Lowering tyre pressure will be effective at stuffing your tyres for little advantage...that is unless you're running 48psi.

and run some toe in on the rear alignment

[rs73]

you only reduce ur tyre pressure if you, say driving a 4WD on a sandy beach so your tyre didn't sink.

Or, you go to drag race and need a little tyre wall flex so you get more grip on hard (straight) launch, not just bumping around the track.

For anything else, pump up your tyres with enough pressure in it, coz they're good for corner handling and less rolling resistance will save fuel.

I'll have a look, but i dont think my shockers are adjustable, only the springs for ride height, so i guess im stuck

youll need to do some more research. My konis are adjustable, but you have to remove the shock, fully compress it, and rotate the rod to adjust the damping, there are no external adjusters so they dont LOOK adjustable.

Maybe have a look at your rear camber, and make sure there is no rear toe out as previously suggested. Might have excessive rear camber.

I would even take it to a suspension specialist, get them to look at all the suspension mods and alignment, then drive the car, and work from there.

Do you have adjustable swaybars? easiest way to dial out oversteer if you do.

[Beeble]

I've got the whiteline kit with adjustable sway bars, front on hard and the rear in the middle. still find that on fast tight corners (eg turning right at lights at around 60, no traffic around!) it has a tendency to understeer just a little, but then to flip into oversteer without much/any warning. can be rather scary and hard to correct, to the point that i have a little less confidence in the car's handling than i feel i should. the rear end is far less "twitchy" than a lot of rwd cars i have driven, but the way it can just snap out on you with no warning worries me.

Question, i guess, is should i try full soft at the rear sway? the shocks are bilstein all round but not adjustable

[Guest Robo's]

Im learning to drive around it, ease the throttle in

[benm]

What type of tyres are u using on the rear? Just coz you have 255/40/17's doesn't mean all that much unless you are using good quality rubber.

[Guest Robo's]

Yoki something, ive just bought the car, maybe the tread has gone off and has lost its stickiness

[KamikazeR33]

could be the tyres

my car tends to understeer a little when fanging it out of nice country corners

in town it does oversteer a little

[slip]

i wasnt going to say anything about the throttle robo, but now that you mention it....

[Guest Robo's]

But compared to a more powerful VN i used to have with old design rear suspension and stock rims, it would exit corners quicker than my R33

[red900ss]

Soften the whole thing up as much as possible then adjust from there to suit your driving style and conditions.

[Nismodified]

Get better tyres. You will find a very tangible difference in the way the car feels, drives, and responds.
