Weight bias ratio, is it always better to have 50:50 even for a fwd car?

Sigh.... it's a stock type-r swaybar....

have you got different tyres?? in front and back??

that weird that an ITR feels oversteering... what other sussy mods have you got??

something is made it like that..

Could be something as simple as cornering technique that makes the back want to step out.

So should i lower the rear tyre pressure and rebound a bit more if my car oversteer when i brakes (no matter how hard) during corners? I just keep feeling that the car will oversteer during corners, no matter i am stepping on the accelerater or brake. But it will oversteer definitely if i tap on the brakes.

Alvin i think what you need to learn to do is set the car up before the corner. What i mean is make sure the majority of your braking is done before you start your turn in. This way the car is balanced as you enter the corner and then you accelerate out of it. If you are on/off throttle or brakes during the corner the rear of the car does tend to oversteer and i think this is most likely your problem.

In turn one and two at QR i do all my braking prior to turn in and then feather the throttle gently through the corner and accelerate hard out. Turns 4 and 6 u can use oversteer to help you corner but use the same technique as above but once you have the car pointed in the right direction tap the brake to provoke oversteer and then accelerate hard out of the corner...

I have to disagree with some of your comments. I have found that by rmoving the spare tyre makes the car quite tail happy when high speed cornering compared to having it in.

In addition to this very stiff rear suspension also makes the car tend to be a lot more tail happy. When tracking my car i have the front sussy very stiff with the rear quite a bit softer. This is because of the weight difference of the front and rear half of the car.

You make the rear as stiff as the front and it will become very twitchy and jumpy and on a track with an uneven surface this is a very bad setup. Allowing more travel at the rear, coupled with the lighter half of the car ultimately results in more grip at the rear.... Trust me a car which oversteers at 140kph is not exactly a fun experience.

Thats exactly what I have experienced racing my DC5R. On the uneven Sandown Circuit in VIC. I Spun at 120kph.

Euge.. i didnt realise lowering the rear of the car balances out the weight!

Too be honest, I didn't think it would do much either ... other than affect the dip and lift when braking, but apparently the rake does do something

gotta love cars and driving.. soo much to learn!
