how did you choose your compression and rebound numbers? I was considering having my shocks redone and getting some custom spring rate springs. But in the end it's like $65 per shock plus shipping, then $75 per spring and I have no idea what length to get the higher spring rate springs, and then if I want to go for the gusto, the coilover conversion kit from ECS adds another $250. So that makes close to $900 and possibly a lot of waiting. I can get vogland coilovers for just a little more than that and no thought. Hmmmm.

And considering the hassle cheaper. Except that I do not think you will feel much difference from what you have today. Rates are in 600 range, but springs are progressive.

If you are serious about this AutoX thing, give us a call and we will build a set of Penskes for you.

I've seen your setups advertised and heard good things, but I just don't want to dole out that kind of money. I have 2 problems with my current setup...shocks have 100k miles and need a revalving, springs seem too soft.

and I believe even though my springs are advertised as linear and stiff, they are neither.

Ask for rebound at 350 lbs at 5"/sec, and compression at 300 lbs. This is a decent AutoX setup assuming you are keeping your springs.

I am making the shock extra stiff to compensate for springs, if you were able to get better springs, we would reduce the compression.

since custom springs have one ID and the front shocks with stock bottom and top perches have different coil diameters. I think the revalving is fine so long as I had A4 specific springs that I liked. I don't like my springs. I don't think there is a spring out there I want enough to revalve my shocks. I don't believe my springs are as stiff as they are advertised because even the cars with H&R coilovers (not ultras) feel more flat and tight than mine. So the revalving would only make sense if I could get springs I liked that would fit the Bilsteins. I don't want to compensate for my springs. I feel like if I'm going to spend money, and have the car useless for most likely a week or more, I want to get it right. Like you said at first it's more trouble than it's worth...just get coilovers. I thought I read some old posts of yours about modifying a current coilover? Was that an old idea before you arrived at your current product? Thanks.

what do you modify...shock rebound? spring rate? If you think ultras are good enough for street with occasional track time, then the off the shelf Vogtlands are pretty much the same for less money according to the few S4 owners posting. I figure even better on an A4 since it's it's lighter. I would however like a little more spring rate in the rear if possible. I guess that if I could land a used et of coilvers, then customs springs might be a possibility.<ul><li><a href="http://forums.audiworld.com/s4/msgs/2095235.phtml">http://forums.audiworld.com/s4/msgs/2095235.phtml</a</li></ul>

Get a set of Vogtland coilovers. Wits some modifications you should be able to fit a linear spring in front. That was my original idea before I realized how much it would all cost.

So, for you I recommend a set of Vogtland coilovers a rear bar and a LSD... in that order.

linear springs. Thanks for the ideas.

it was an improvement but not enough to justify the cost or effort.

I'm going to buy a set of used stasis coilovers at somepoint and i think you should do the same.
