with the koni yellow adj. shock or any adjustable shock for that matter what is effected by increasing the firmness of the shock? the shocks compression? it's extension? or both...i ask this because i have koni yellows just on the rear..my thoughts were to increase the firmness when at the track to minimize the squating of the rear end...but perhaps i want these on the front aswell if they minimize the extension of the front?

im not sure exactly but i can tell you this. my friend blew one of his konis by smashing into a curb and had one koni one oem in the front. i was shooting a video for class and when he tried to do a burn out guess which tire left a dark long track? the koni side.

I have Koni's front and back w/ Comptech springs. The firmer I have the konis set, the less squat I get from accelerating and braking. Definately a difference over stock.

Koni yellows are rebound adjustible only. The speed at which the shock extends is what is affected. I have them front and rear. Increasing the stiffness on the front ones will reduce squat (actually reduces front end lift)

typeR

thats what i thought....

edgalang

Good to know...then that means typeR has them on backwards.

typeR

exactly...but thanks though

mattg

for the track, i would go all the way firm in the back and in the middle on the front.

typeR

koni recomends full soft rear full stiff front

AQUI NO!

that doesn't sound right. On a fwd car u want the rear end of the car to be stiffer than the front. This promotes over steer, what ur describing would promote mad understeer, a big no no on the track. try one full turn up front and 1.5 in the back.

typeR

the track were talking about envolves going straight for a 1/4 mile then coming back and doing it again

mattg

koni recommends how their shocks should be used on a fwd car at the drag strip?

i thought you wanted less squat and weight transfer to the rear, which is why people jack the rear end up.

AQUI NO!

ahhh, nevermind then. I guess it makes sense in that the front end of the car wouldn't lift as much and would result in less wheel hop.

typeR

they do and this is what theyre trying to achieve...the stiffer setting is rebound or extension not compression...so the rear end squats under load and by setting the rear stiffer you just slowed the rate at which the shock tries to push the rear end back up...the compression rate is fixed...so we set the fronts full stiff slowing how fast the front shock will extend and the rear full soft allowing then to extend back as quick as possible getting the weight back on the front end...

mattg

i didn't know the compression was fixed. i wonder if the teins are the same way?

AQUI NO!

rebound and dampening is adjustable on the teins SS and tokico illiminas, just not independently of each other as in some of teins more high end products. Heck, on some of their coil overs you can adjust the spring preload, height, rebound and dampening

Let's just be clear here, because the name "shock absorber" is basically an oxymoron. I'll bet there is more than one person here who thinks a shock absorber absorbes shock as the wheel travels upward.

Wrong. Dead wrong.

The spring absorbs the shock on the way up. The purpose of the shock absorber is to put the wheel back on the ground after only one spring cycle. The spring, by its very nature, wants to keep cycleing in smaller and smaller oscillations.

This is why you can tell people who have worn out shocks because their wheels are always and constantly hopping off the pavement.

If you find this hard to believe, try this: grab any new shock and collapse it. It will be relatively easy (because the coil spring is designed to do that work). Now, extend the shock. It will take a lot more effort.

Zapata

well put and exactly correct!

Ok, so for Tein SS Coilovers then which have adjustable rebound and dampening ... what would you recommend? Same as the Koni's ? ... Full on the rear and none on the front?

I've got the EDFC for mine so I can probably just keep toying with it at the track but I figured I'd ask

AQUI NO!

for 1/4 mile, same as the konis i guess, full front, none rear. For road course or autox, start at 10/16 clicks on the back and 8/16 up front and go from there. i run mine for spirited driving at 12 front 16 back.

mattg

i want allmotor to confirm this. i thought it would be better to have the front somewhere in the middle and the rear all the way stiff, at least with the teins.

when i ran that 2.08 60' i had the fronts at 10 and the rear at 8. my deck tray was in so i couldn't adjust the back.
