Coilover Traction Loss

[TypeSexy]

hey guys

i have an issue that's been on my mind for awhile.
When i take the car out to national park and have a session of spirited driving, i experience loss of traction around corners when the road get's bumpy. Not only is it annoying its dangerous as well

I have coilovers that's pretty new and no issues with that.

How do i resolve this issue? change spring rates? or is the coilover the problem?

Currently running stockiesd with32psi

Is it a Type S?
My answer to that is NO LSD………

[TypeSexy]

yes it's a type S

really? no LSD would affect it that much? fark me

its a B.C BR coilover as well

[Zakarados]

No LSD will only cause this if you are getting inner wheel spin on powering out of exit?

Did you have this problem before getting the coils? I dont have this issue running stock sussy.

What coilovers are you using? What spring rates? Any other suspension modifications? Hard to say for sure what in particular is causing the issue, even a stock DC5 isn't the most compliant car on a bumpy road.

When you say loss of traction do you mean forward acceleration traction, or lateral traction as in cornering?

[freakygeek]

Incorrectly set damper rates will cause that kind of issue to a certain extent. Say for example, there is too much rebound damping, the wheel will not return to the road as quickly after the spring is compressed after a bump, therefore loss of traction will occur.

That is a very simplistic example of course, but it forms the basics of setting spring and damper rates correctly.

Definately need more elaboration.

If the loss of traction is specifically related to the bumpy road and traction is fine on a smoothe surface corner then it definately isn't the LSD.

First thing the came to mind was either your suspension is too stiff or your shock's rebound rate can't handle such frequent bumps. This is applicable to both cornering and powering out.

As Temp mentioned

Usually the case is that your setup for the road is too stiff, hence the coilovers not absorbing much of the impact causing understeer/loss of traction.

Try a softer setting for the damper as i know with bc's you cant change the spring rates.

When i take the car out to national park and have a session of spirited driving,

this is your first problem, expecting your car's 'race bread' suspension to perform well on low quality roads...

your second problem is that it is likely that you are 'over-driving' your car, so that it is actually your fault that you are losing control of your car - because you are not compensating for the stiffer suspension, and the effect that this has on levels of grip...

that is, instead of saying

i experience loss of traction around corners when the road get's bumpy

you should be saying

i lose control of my car when i try to drive on bumpy surfaces without compensating for my lack of experience/incorrectly inflated tyres/'race-bred' suspension/etcetc

um the only correct way to change spring rates, is to change the springs...

BC Coilovers - BR series
Front Spring Rate : 10kg/mm (558.7lbs/in)
Rear Spring Rate : 12kg/mm (670.4lbs/in)
no other sussy mods
my damping settings would be useless as every coilover is different.
But i had it on "hard to soft" so that could be to blame i think. Ill have to try it with soft settings.

thanks, im guessing this is the problem as well

i want the car to preform the same on a track as well as a bumpy road.

they come in set spring rates you are right, ill just play around with damper settings, i thought maybe it could be something else.

tinkerbell, you are a mod on this forum and you post non helpful comments. why you mad though?

that is, instead of saying you should be saying

My names tinkerbell & i Suck!

[tinkerbell]

this is a unrealistic expectation to have.

[TypeSexy]

this is a unrealistic expectation to have.

howcome?

is it cause of the type S suspension set up or what?

i remember stock was the same as well with more body roll

srs btw

[stevan]

having harder suspension on bouncy roads will cause the wheels to skip over bumps rather than "damp" them while maintaining contact path. softer settings will keep the tyres on the ground but will increase roll.
