Default preload

Anyone have a pic of the lower adjustment bracket on say a B6... I'm just curious how it works in regard to preload... and I have yet to be able to get a good look at it.

Just leave the B6's alone and install them.

They come preset.

Do not worry about preload since you apparently think it has something to do with the type of suspension you have, rather than a spring.

EDIT:

Not directed at you, but:

Why do people want to get suspension with as many adjustments as possible if they do not know what to do with the adjustments? It's far easier to do harm than good.

That said, could someone who did put the a set of B6's on and finds them to understeer even at the most radical shock settings. Is it possible to adjust preload to change this behavior?

Understeer is largely related to the relative spring rates F/R. Adjusting the dampers to the "most radical shock setting" can make a spring seem stiffer - but at the expense of proper damper function (i.e. overdamped = bad)

i don't have a set of b6's not plannign on a set either was prolyl gonna get the b2's I was jsut curious how that lower bracket was able to adjust preload. on the b6 and above

If you need to add significant preload to a spring, it is a sign that you should move up to a spring with increased stiffness.

What are your current rates, thread hijacker?

Spring preload is used to setup a spring for slightly increased stiffness.

As stated above, it is a better choice to use stiffer springs rather than try to add preload.

Too much preload just places more burden on the shocks.

Adjustable spring perches give one the ability to play with spring preload.

Preload wont affect spring rate or how the car feels on track - other than the fact that you can use spring preload to cornerweight the car. And if your shock is ride height adjustable, thats the *only* reason to touch the spring preload perch.

RJ - who agrees that too many adjustments is a bad thing, and hasnt touched his shocks since VIR in february

WHen I said most radical I meant front settings as soft as possible and rear as stiff as possible to purposely overdame the rear to reduce traction. The Theory that has worke don all my other shocks just didn't seem to work this last time I was racing.

My current rates are 10/6 (Street). I have considered going to a 12kg/mm rear spring.

the B6's have a spring perch that casn change the preload on the spring like you mentioned. There is then a mount that will allow the height of the shock to be adjusted without allowing the preload or the stroke of the shock to be changed. YOu really should see a shock to better undrestand thes. The mounting backet is threaded and allows the shock to spin down into it.
