Less front wing, More rear brake bias, Soften rear suspension, Stiffen front suspension, Try not to jump *on* the brakes and leap *off* the throttle, Smooth = speed? 8-) *Peter* 8-) (NB: remove asterix to e-mail)
Hi Sean. Just citing oversteer is a little broad. There's different kinds caused by different things that have different solutions. High Speed Corner Oversteer - neutral(ish) acceleration or braking Try more rear wing, or even less front wing. This type of OS is more of an overall balance thing rather than just one end of the car. That's why you can actually fix it by adjusting the front end. Braking Into Corner OS. This is almost always caused by the rear brakes locking up inducing OS. Adjust your brake balance more to the front. If you like to brake deep into corner while turning you'll find you'll need the brake balance moved towards to front quite a bit. How much depends on how many braking Gs you're pulling. E.g. Braking from a 6th gear 206mph straight into a slow 1st gear chicane will require a very forward brake bias if you want to be able to steer the car while under such braking. Accelerating Out Of a Corner OS. This could be either-or-both, lack of rear end grip or being too enthusiastic with the accelerator. High speed grip is a combination of mechanical grip and wing grip. The faster you go the more its to do with wings and the less with the mechanics. Low speed grip is more just mechanical grip. Mechanical grip is increased by softening the suspension via the various adjustments available. High speed grip is increased by increasing the wings. If you're over accelerating try to use a higher gear to accelerate with. This reduces the gearboxes' torque amplification effect and makes it harder to spin the rear wheels. Or even adjust you low gear ratios accordingly. Also feed in the power by degrees when accelerating out of a corner. Especial a slow corner and especially especially a slow corner that's going uphill. ( The greater the load being overcome and the more the various forces are off-set from one another the greater the rotational force created when accelerating. Corners and hills exaggerate these rotational forces. See http://www.powerup.com.au/~philmak/GP2MAN/AcelInGp.htm ). Cheers Phillip McNelley
When are u oversteering?, On entry, mid corner, turn in, exit, hi speed or low speed corners?? etc etc??
