Can any tuning Gurus help me reduce Outside rear wheel spin on my F430 Scuderia? Fries it like a bitch...

Adding ballast?
LSD tuning?
Reducing power?

All of the above? :dunce:

Currently Ive got Stage 3 weight reduction, Aero, LSD, Exhaust, Chip and Stage 1 engine tune (plus clutch, flywheel, RSofts etc)


Been reading alot of the LSD threads and it still seems that its more effective for Inside wheelspin rather than Outside...

(Oh, and of course simply driving it better helps xp )

Thanks guys! 👍

I drive mine on sport softs, you just need to work out LSD settings and dampers and that wheel spin should quiet down. Most of these high dollar sports cars come with nice clutches and flywheels, I actually see lap time drops upgrading some of them, so you should also test each component individually because some will just make the handling sloppy and take nothing off the lap times.
 
Try my F430 setup if you like, see if it improves your situation, and if it does, note what I did differently. Link is in my sig, Lion's Den Peformance.

Tell it to my newly purchased McLaren F1 :indiff:

I believe you, actually.
I don't own the McLaren, but I do some 'spec' races online from time to time, where everyone is in the same car. The host chose the McLaren, and oh my god, you can't touch the gas without the outside tire spinning uncontrollably. Throttle steer, is an understatement. It was absolutely ridiculous.
I'd start at the old 5/5/5 used to help tame the crazy unstable cars, like the Zonda, matmut etc. Then get the suspension in the ballpark with that LSD, before going back to LSD and then fine tuning the suspension.
But you're the tuner, not me :p

Dont listen to him. You want to do the complete opposite.

Two to one against you in this thread already, Veyron. I'll make it three. Lowering the Accel LSD can help and raising the initial can help. Maxing the initial can be overkill.
 
To fix outside wheel spin you lower LSD acceleration...

Higher = more torque to outside wheel
Lower = more torque to inside wheel

You want lower LSD acceleration.

3 against one has nothing on results.

I am doing a 6:26 on the ring with a 7/26/18 setting with the car understeering.

Initial torque is the last setting on touch usually, it fine tunes my other settings.

I usually setup braking sensitivity first at this determines how well my car exits corners and is a straight line to receive acceleration torque. Then I adjust initial torque so that the car can make fast sweeping turns using as little brake as possible without over or under shooting its driving line. After I find the first two, then you find the acceleration sensitivity to complete the setup. However, settings that work on one track don't necessarily work as well on the next, so even LSD can have limitations just as most other facets of the tune process.

How about I know how to setup my car. I start at 10/5/5 and increase accelertaion and reduce intial torque from there and every car is different.

Doenst know how to setup their car, doesnt know how to setup their car, doesnt know how to setup their car. Take your pick.

Since you havent posted evidence of results, you have nothing to back yourself on.

My evidence is based on the fact that you said "lowering LSD Accel is wrong" followed by posting your personal LSD which is, guess what? Lower than the default setting. So, that's where your 3 word choices came from:
Ignorance: You didn't know default LSD was 10/40/20
Irony: Your LSD Accel is Lower than Default
Hypocrite: Telling me I'm wrong while using the same theory

Even further shoving your foot down your throat, your next post displays more clearly that you begin with the absolute minimum LSD Accel possible, slowly working your way up to what you feel best for you.

I'm not sure how to make it any clearer to you, so whether you comprehend it or not, lowering the LSD Accel was the correct advice despite you telling us all we're wrong.
 
Bit of a bump but on-topic...

Been messing with the tune, and some plain ol' negative camber on the rear (used with extremely rough LSD settings of 10/10/10) has really helped the situation and to calm down that outside rear wheel... Left spring rates stock as they are probably already pretty decent on a Scuderia...

That, and improving my driving technique has probably helped too...

^ Glad to hear you're making progress. Sometimes adding a bit more +ve rear toe helps reduce wheelspin, too.

Ok cool, I'll give that a go too, thanks.

The LSD and that Negative Camber (and my driving :-p) have actually brought it in line ALOT, to the point where it feels as though it could handle more power now... though I'm thinking that I prefer the restrained feel of the car now...

It's still lightning fast, and in this particular case, I reckon feeling a little restrained isnt going to piss me off as much as that damn Outside wheelspin...

Maybe now I'll just look at dialing out a little understeer and this thing will be set! But thats for another thread...
