Snap oversteer on Ferrari 330 P4

[Jaywalker]

I searched but couldn't see anything on this.

I was getting serious snap oversteer (on braking) on the Eiefel track in the supercar seasonal on my P4, even on R3 tyres. I remembered reading somewhere about ballast positioning creating oversteer if you move it to the rear. So I applied the opposite & added 5kg & moved it all the way to the front. And just like that, it was gone!

Is this an accepted remedy for this issue with this car? (And any others?) Also, does reducing deceleration sensitivity on the lSD & increasing rear brake bias also help with this?

I reduced initial torque down to 5 and that got rid of most of it

Cool. I'll try that. Thanks for the input.

I'm working on a full tune for this car to post in the Vintage Tuning thread, not quite happy with it yet, but I got the drivetrain about perfect, and it is if I can remember offhand 19/9/24. It will still slide a little bit under hard acceleration in 1st gear and the lower RPMs in 2nd, but otherwise it handles like a dream.

Cool, thanks JL.

No problem bro. The full tune will be up before long if you want to give it a go.

Sweet. Most definitely will. Where'll you put it?

the Vintage Tuning thread (Link in my signature). We were going to save the old race cars for after we finished the street cars, but there is a good bit of interest in the Ferrari and Mark IV. Don't expect the GT-40 tune any time soon, because even though 200MphFord has a brilliant set-up for it he is very stingy about it lol

Nice page, JL. Gotta try some of those tunes, since I have most of those cars...

Thanks man. The GT350 is being redone as I had a bit of a break through with it, but everything else should be perfect.
