Quick way of adjusting suspension and LSD (for ppl who don't have time)

[Meltac]

Hi all,

I was wondering whether there is a non-time-consuming approach to adjust suspension and LSD, or at least some quicks wins / low hanging fruit.

I've read a couple of tutorials and threads regarding tuning these things, but they all sound very time consuming, with much trial-and-error, personal taste things, race-depending settings etc. Most of them say "start from here and work your way through until you are happy with a result". I don't have that much of time, unfortunately.

I don't need the perfect match, the sweet spot of tuning or anything, but wish to learn a couple of basic rules or recommendations for addressing a set of common problems such as under- or oversteering.

Something similar to these simple rules (that are also not perfect in every case but fit the vast majority of cases):

• Against understeering, raise front downforce, lower front anti-roll, raise rear anti-roll, lower initial/acceleration torque
• Against oversteering, raise rear downforce, raise front anti-roll, lower rear anti-roll, lower initial/acceleration torque

Can there be given similar basic recommendations regarding the other suspension settings and for the front/rear LSD of 4WD cars?

This, in general. Plus particularly I would be interested in a way of fighting oversteering apart from increasing rear downforces, when the latter should be kept as low as possible in order to gain top speed and/or help against tire wear.

Any hints are welcome

Great, that's a starting point. Thanks for the quick reply.

What about Front/rear torque settings on 4WD's? And what about suspension settings?

There's loads to read for that type of thing,
I recommend this page as one of the many resources out there.

Thanks, I'll check that out. Although on first sight it looks like one of those time consuming things again.

Shameless plug, but I created a video guide to differential tuning.



When it comes to 4WD it depends on the car, but here's a quick rundown.

Initial Torque
Low values make the car more agile, high values make it numb but more controllable

Low Initial Torque Front, High Rear = Unstable under braking, understeer when accelerating
Higher Front, Low Rear = More stable when braking, less turn-in
In most cases, I set it between 5-20 at the front, and 5 at the rear.

Acceleration Sensitivity
Higher values send more power to the outside wheel.
Low Front, High Rear = power oversteer, like a RWD
High Front, Low Rear = more understeer, like a FWD

Braking Sensitivity
Higher values are supposed to make braking more stable at the expense of braking performance. In almost every single case, I have it set to the minimum because the brakes feel sharper and the difference to braking stability is quite small.

That's a very useful piece of information - many thanks!
