dampers complex, please help

[Ceolix]

guys please help i don't know how dampers work in gt5
i looked through here they say a softer damper on front
will make the car understeer / a softer damper on rear will make
a car oversteer.

although i changed the values of the compression and the cars acted normally.
they didn't oversteer or understeer, it made no effect.
so how can dampers increase or reduce grip?

i also don't understand why a damper needs to extend.
my mind is already a mess thinking how i could understand this but
i simply cant

The main purpose of dampers is to manage weight transfer(together with springs and ARB).

When you brake, front compression/bound and rear extension/rebound regulate how fast the springs compress/extend on the front and rear respectively.

Front extension/rebound regulate how fast the nose returns to it's static/normal position.

The rear compression/bound regulate how fast the car squats under acceleration.

The effects of settings and adjustments depends on drivetrain, grip levels, mass of the car, power/torque, brake sensitivity, driving style, spring rates, ride height, nature of the driving surface, and a myriad of other things.

Go to the tuning forum and read some of the guides for a more comprehensive explenation.

if a extension damper is too stiff/light it will make me understeer
right? same goes for compression

If it's too light for the spring rates you are running the car will bounce over rough surfaces making it lose grip. If it's too stiff it will not let the car return to it's natural position in time for the next corner. It's a little complex and possibly the only thing in car tuning that can't be dumbed down.

You have to balance it with your spring rates and ARBs for the certain track you want to run. It is possible to tune a relatively soft setup to use universally though, I've done it before, but it won't be the fastest if you're running in a group or trying to run in the seasonal events.

i dont get other thing
10 is stiff or light?

To make it easier, forget about damper affecting grip because that is an indirect effect. just focus on what they do directly, which is to adjust how quickly the spring moves.

For instance, if you have a lot of oversteer under braking, you would increase the compression force of the dampers up front. This will slow the compression of the damper and reduce oversteer.

and to answer the second question, 1 is the least resistance and 10 is the most resistance.

yes it looks like compression adds excessive WHP but
it doesn't make sense. why it would oversteer if the weight
is being pushed to the respective wheels while turning?

 

[Voodoovaj]

WHP?

Anyway, It makes total sense. Think of each tire like an anchor. You want to dig that outside front tire into the ground so the car will dig in and turn. If you dig in too much, too quickly, you'll get over steer.

 

[mistersafeway]

WHP generally stands for Wheel HorsePower if that's what you were asking, if not, I'm with you on that confusion, as it does nothing of the sort..

why would it understeer/oversteer if it digs faster?
wasn't it supposed to turn faster as well?
or is it because of the suddenly weight transfer?

 

[Voodoovaj]

You should start google-ing

Handling is all about balance and not make abrupt changes to weight distribution.

The higher numbers are stiffer, lower are softer. Usually I keep both front and rear the same and usually click up one or two numbers from stock. This Praiano genius seems to really soften the rear shocks and raise the rear end to make MR cars handle, not realistic but works well in GT5

Well, it takes all kinds. I don't use his tunes. I tend to have similar set ups on cars that over steer, with the exception of the ride height. I do the reverse. The lower your car, the less roll you get, but you sacrifice suspension travel. If I under steer, I do the opposite. You find the springs are where you should focus with the dampers being a means to control that spring movement.

 

[Ceolix]

Compression:

light: harder shocks --> understeer
stiff: lighter shocks --> good handling?


extension:

light: ?????
stiff: ?????

i have no idea how can extension help on handling
but it makes sense to me if compression works that way.
if someone could explain me this straight...
it's a very hard theory for me.

The Tuning forum is the place you really need to be for this kind of help but here's a link to a write up that Motor City Hami did a while back that should help > click here <

don't take it wrong but it doesn't really explain what extend and compress do :/

No problem, I just thought it may be useful and was really just trying to point you in the right direction which is the Tuning Forum!

bump please
still needing help

I'll give it a whirl. Though as others have suggested the Tuning Forum is the proper forum for this type question & info.

Compress = resistance to the frame going closer to the road surface.
Extension = resistance to the unsprung wheel assembly/axle extending to follow the road surface as the frame moves away from the road surface.

Bigger # = more resistance = stiffer ride.
Smaller # = less resistance = softer ride.

Hope this helps!

too much compression = suddenly transfer weight -> pressure on tires -> understeer?
too much extension = springs cant compress -> understeer?

i hope it's this the concept

Small correction.

Big Compression Damper number would mean that end of the car will resist compressing its springs, weigh transfer will be delayed. The dampers restrict/slow the spring action.

Under/over steer is affected by many factors and the damper setting may not universally correlate depending on drive type & weight balance to name but 2 factors.

Motor City Tunes's post (about 1/2 way down) sums it up nicely IMHO.

yes, but when i meant much compression
i meant fast compression, with 1 valor

thanks for your help though, i think i got the idea
