Coilover Adjustment Help needed (pic included)

[brownyboy]

Right, basically took these off yesterday and was just about to put them up for sale.

Replaced with standard shocks with lowering springs. Obviously handled alot better when on the coilovers and got me thinking that there must be away for them to be adjusted so they dont rebound so violently as this is the only reason i took them off in the first place.

From the pic does anyone know what I should be adjusting to make it so the spring does not rebound so quickly, i basically want to soften it up if possible.

My plan was to bring A and B further down towards C, thus making the spring less compressed

Comments please guys

Making the spring less compressed will just make the car lower though? The weight of that car will still compress the spring, the adjustment rings just set the height?

what if i move A and B down and then also bring C down, if that makes sense

you won't change it unless you change the spring or the damper rate

If theyre underdamped to D2 offer a softer graded spring set?

 

[Fred@BTM]

move A/B away from C and see if that helps, but i doubt it

Are your D2 coil overs the same as the ones here?
If so then you should be able to adjust the damping according to their website

the perfect coil over system which is fully adjustable with a 36 point damping adjustment, adjustable ride height, and even camber adjustability

Or are they a version that has fixed compression and rebound damping?

I'm trying to learn how to set up a coil over system myself before I buy some but at the moment the only practical experience I have is with motorbikes.
I do know that with bikes, if you set the preload too high then it would bounce like a b**ch over bumps which is what you seem to be describing.

I used to work the preload out using the mass of the bike on each wheel (using a bathroom scale under each wheel), the spring rate and length of suspension travel and doubt it would be much different for a car.

I expect some of the more competent club members will be able to tell you what the weight is at each wheel then all you need to do is give D2 that info together with the details of your coil overs and then they should be able to tell you what the correct preload should be.

You definitely don't want the preload set so high that the springs becomes springbound before the bump stop.

On you pic C looks like the ride height adjustment, A is the preload adjustment and B is used to lock A into place.

Like you said, If you release B so you can move A towards C then that will reduce the preload and make the car less bouncy which should do until you know the optimum settings.

I'll keep my eye on this thread as I was looking at getting some D2 coil overs myself.

i tend to agree, C look like bump/jounce adjuster, try turning C all the way one way then count it back see if there are 36 clicks like internet suggests.
