Cure Lift-Off oversteer in the LP640?

[peter_vod69]

Hey all,

I did a search, but didn't find anything much, and was wondering if people had any clues on a suspension setup for the LP640 to cure the lift-off oversteer? I know that it is an inherent trait of the car as standard, (with a big engine mounted fairly high in the chassis) but I'd guess there must be a way of fixing it.

Anyone?

Any Aero kits, (spoiler).

Yea, the positive rear toe will help alot from the tune linked

Cheers all - I'll start with rear toe out, though it kinda goes against my instinct. I'm just doing a mildly modified LP640 (aero pieces, exhaust, intake) but the handling is just, well, exciting to say the very least.

The problem with toe is that it will affect the car in ways other then when decelerating also, meaning the car will then under-steer when you're not decelerating.
I used LSD decel to mostly cure the problem. 25front / 5rear, also having a stiffer rear shock extension the front can help too, to a lesser degree.

Those are the only two things I know of that will affect deceleration handling without affecting mid corner handling and on-throttle handling along with it.

I was thinking of stiffening up the rear anti roll bar too, to minimise that moment of inertia/weight transfer.

like csl said: stiffen up the rear extension and didn't say: stiffen front compression

the lsd decel trick should work too everything else (like he said) will affect handling in other situations.

 

[Poontanir]

personally I would go a different direction. Stiffen the front anti roll bar and soften the rear, this will reduce body roll without reducing rear grip (don't over do it). then stiffen the front bound (shock compression) to slow forward weight transfer and slow the oversteer.

Here is my tune for it. If you don't find it amazing something is wrong with you https://www.gtplanet.net/forum/showthread.php?p=5535816#post5535816

I like some of the ideas being thrown around, but first I would ask, what are your following settings...
Front
-Toe
-Spring Rate
-Ext.
-Ride Height
Rear
-Toe
-Spring Rate
-Ext.
-Ride Height
LSD
-Inital
-Braking

Since this very last update, it seems the smallest tune settings can make or break so many handling characteristics in the game. I also noticed that my online cars behave the best now with 0 front toe, and 0 front camber, where even +/-0.1 eiher way would make the car slide around where I wouldn't want it to.

For lift off oversteer, I'd have my rear ride height higher by 3 notches than the front, reduce rear spring rate , have a high IT LSD and low ACC setting, (aka 42/9) and unrelated, but reduce the rear brake bias down to 2 or 3 max. Also, having bad front car suspension settings will also wreak havoc on the rear.

You know the accel setting won't do diddly for lift-off over steer though, right?
I can see we clearly have different beliefs through all your suggestions, but surely you don't think accel LSD will affect the car when you're not touching the throttle, right?
