Dialing Out Some Understeer On R33 4 Door

[lookingforboost]

Hey guys i want to dial out some understeer on my R33 4 door it has the following fitted

Front camber kit

Castor rods

rear camber kit

rear toe kit

sub frame bushes

whiteline Rear sway bar 22mm set on hard setting

Whiteline Front sway bar 24mm set on medium (cant ajust more need the sperical bearing link kit)

has kyb shocks and lowered springs but changing to HSD HR coilovers

Its not that bad and heaps better then it was before but i just want to balance it so i have even understeer to oversteer or tiny bit more oversteer to understeer

Alinment settings

2.5 front camber

1.25 rear camber

1mm toe rear (2mm total toe)

0 toe front

+5 front castor

Thanks guys

With your swaybar and front camber settings it shouldn't be too understeery???

Maybe better tyres?

Is it a road car? what tyres?

Put the front bar to its softest setting.

Add air to front tyres.

Put the stock front sway bar back on

I have only had time to fit my rear sway bar so the front is standard, and boy it oversteers like a whore!! Would be a good drift car haha

Yes its a Road car

Just some low budget 215 45 R17s on 7.5" rim

running 40psi front little bit better but still bit more understeer than over steer.

i cant set the sway bar softer until i buy a new link kit for the front because the stock links wont reach the softest setting hole on the bar

i have picked up some BC racing BR series coilovers i am going to fit these and see if there is any change because i think one of my front shocks is leaking

Stiffen the rear bar up it may help but when your looking for grip and using budget tires 90% of the time your pushing shit up hill.

Don't touch the front bar If your happy with the rear end of the car.

Those won't help.

Those will probably make it worse. Stiffening the front end will only increase the understeer characteristics.

i am just saving up for some Federal 595's or some KU36's for the front, its already on the hard setting on the rear so i cant go any stiffer than that.

my lowered springs are about 1.5 inches lower at the front then the rear and the rear have a softer spring rate would have affect it?

[Harey]

Yes softer rear suspension will contribute to understeer.

I would recommend you put on Bilstein shocks at the front if your current ones are buggered. As said previously, stiff coilovers will just make it understeer more.

Plus stiffen up your rear suspension, eg stiffer rear springs.

Less rear spring actually makes a car gradually oversteer as opposed to to much spring which makes it snap oversteer.

Too much front spring will cause understeer, but usually mid corner not entry.

If we are talking about a road car and your complaing of understeer, go buy some GOOD tires and watch the problem disapear. You could not possibly be pushing the car into a window where sway bars and springs are going to effect the handling if the tires are budget........

Yeah better tyres are a priority at this stage just deciding on wheels before forking out for tyres.

its good on the street but poped up when i took the car drifting at driving sports event, i am fitting up the coilovers because the car setup i thought was to soft and felt a bit boaty trying to follow through to the next corner.

once i get better front tyres do you guys think i should increase front or decrease front camber?
